hello all from edmonton, alberta

Iron

Thanks Mr Miller & Lauren

?Is thier a way to dowenload the sound similar to downloading the slides?

i use interrrupts for sensor data collection

low  power is more cosidered in current application

current clock rate is 10-20 MHZ

my algorithem is focused on sensor control,I am repeating the lrcture now due to better conditions

timing and I/O intrrupts

@Encinitas_Traveler: Check out the July 15 - 19 class on Real Time Kernels. Sounds like what you are looking for.

Gold

Another good session. Thank You Warren and Lauren.

Iron

Yes, we use interrupts for timing, for collecting sensor information, entering/exiting low power modes.

Iron

High performance or low power more important? Depends on the particular situation. High performance for algorithms, low power for long battery life. As you said, there are design trade-offs.

Iron

Clock rates or some target MCUs are 50MHz, 12MHz. Others. (Numerous embedded designs)

Iron

Our designs focus on sensor interface to acquire vital signs and interprocessor communitcations.

Iron

Hi again. Catching up after my meeting.

Iron

? You covered hardware interrupts, but I didn't hear about priorities. This opens a whole can of worms that get into deadlocks, semaphores, resource starvation, etc. I'm pondering the question of whether something like FreeRTOS would help in my specific case or whether it eats too many resources. Will this be discussed in this series?

@BADHABIT

Sorry, I misstyping, I want to say Cortex the special brand of ARM.

Iron

Sorry, misstiping I want to say Cortex :-)

 

Iron

Posting very slow/intermittent today. Strange.

Iron

Posting is very slow/intermittent today

Iron

use interupts for timers, i/o ...

Iron
Why? A cotex is a bloody tampon and so was cortez
Iron

Someone know why the Cotex gamma received this name (in wikipedia son´t clear it)?

Is only by curiosity, some collegues say that's for the conqueror Henán Cortés, but I think that will be a bad election.

 

Iron

See you tomorrow!! Thanks so much!!

Iron

Until tomorrow then...thanks for the lecture and Q&A..

Reference: http://en.wikipedia.org/wiki/ARM_Cortex-M#Cortex-M4

Warren: The ARM Cortex-M4 is also a superscalar v7 architecture that is complicated and it is becoming a common MCU!!!

Warren: The stuff under the hood on the ARM chips is VERY complicated!!!

Hundreds of registers...out of order execution, multiple ALUs, etc.

Thank you. Good stuff.
Iron

Thank you all. This is very helpful stuff for me.

Iron

jjrochow- I don't know the internals of the v7, but the ARM docs are typically very helpful in understanding how the CPU is architected...

Iron

Warren: I always have more questions than answers.

jjrochow- The best way to work up to being a blogger is to start posting comments to the site. That way the editor gets an idea about what you have to say!

Iron

Thanks Warren - covered a lot today! [4th post try a charm? - Flash is SO fun ...]

Iron

? Warren do you know the internals of the v7 architecture ARM designs? e.g. the Cortex-A9?

Thank you Warren.. see you tomorrow. 

Iron

@All- any other questions? Just about time for me to go. You can save any other questions for tomorrow if you want.

Iron

Random logic is putting together logic gates to perform the computation on the data stream that would otherwise be done by an instruction.

Iron

jjrochow- Random Logic is a funny description. Glue logic (not state machines) might be a better description for it...

Iron

jjrochow- The editor on the site is Rich Quinnell. Email or message him from the site and let him know you are interested. I'm sure he would get back to you about it....

Iron

I have used pure asm with some random logic assist in a case that needed the performance and we couldn't push the clock up any higher.

Iron

jjrochow- Yep the trend really seems to be towrd high level language implementations. If can really help when you have communications ports, file systems and lots of code to write to 'pull in' a simple OS and just code in Java or C+...

Iron

? Warren would they let me blog on that site??

Checked it out yesterday... Very informative web site. Thanks

@All- it is a site that covers all things MCU oriented. Some great blogs on useful example designs and other important topics. I'm one of the bloggers (full disclosure!)...

Iron

Thank you folks!!   :)

In fact, it seems that many are using FreeRTOS and linux with C and C+ (and even Java) in embedded products these days.

@all- Microcontroller Central is here: http://www.microcontrollercentral.com

Iron

Bob Loy- Cache can use content addressible memories, usually just for a look-up table however noy usually for the entire cached word (too expensine in hardware).

Iron

Personnal experience is that almost noone uses pure asm in products anymore..C ans C+ are used mostly with a heavy emphasis on C. (emmebedded products of course) E.G. Apple uses Objective C in their IOS products: iPad, iPod, iPhone, etc.

Warren, do you mean "microcontrollercentral?"

@All- If you are interested in development boards check out Microcomputer Central. Some good blogs there on using evaluation boards...

Iron

Another hint: subroutines that are only used once, ought to be made inline since that allows the cpu to overlap instructions better. etc.

WherleyBird- Using Assemble can reduce your memory size which can reduce the device cost. Development cost is perhaps incorrect sine the time to develop may be longer with Assembly..

Iron

Thank you Mr. Miller.

Iron

Typically one does the high-level logic, even interrupt logic in C or C+ and then looks for places/subroutines etc. that could be made more efficient by a little hand-coding in asm.

GStringham- This came up in yesterdays chat too. Think of the CPU as just the part of an MCU left over if you remove all the peripherals..

Iron

? RE slide 10 - Are those cache examples Content Addressable Memories?

Iron

jrochow: Thank you! Never heard of that before. I can see where that would be useful if one is doing an RTOS design.

gamatec- I have not tested the COREMARK benchmar but there is good info on it online.

Iron

A good debugger environment is essential for development of embedded code. Debuggers will correlate the source to the running code and let you single step display variables and break, etc.

I think the major confused of everybody it's to learn a line of compiler with startup kits to maintenance in time, because in pass to many years people wants to make to study some else more complex kits, an example, is with microchip with his 16Fxx an the next range of micro use 18F with C18 it's very diferentes! teh architecture!

Iron

You made a remark about an MCU vs. a CPU. What is your distinction between the two?

Iron

Typically a profile for a piece of code will show time on the vertical axis and memory address on the horizontal axis.

? why does using assembly over C reduce development costy?

? are you tested the COREMARK benchmark library, if yes can you give us some point of view ?.

Alaskaman66: A profiler is a debugging device that shows the relative time spent in sections of code.

Thanks Mr. Miller, of to work now.

Hear you tomorrow.

Iron

@RPM

Yes, I was aswering the question to Alaskaman66.


Thanks.

Iron

Dev.khan: Use a profiler to see where you need to use assembly code.

Alaskaman66- Basic can target other MCUs but it is typically used as a learning tool (like for the Stamp).

Iron

?  Mr. Miller:


Can you provide at the end of the week some development boards to start with?

Iron

@Camarillo, Look in the archived class by Fred Eady on Basic 4 Android Way June 24 - 28. It's one example of Basic. You just need a compiler.

Gold

Dev.khan- We will see in future classes that it is best to know a bit of assembly. You can typically use C for the vast majority of you design unless you are very cost constrained...

Iron

Tpyn: Out of order execution ought not affect your code.

ARM Cortex A9 has 37 registers, but underneath there are hundreds!!

tpyn- I have not had to code for out of order execution except for needing to put No-ops after jumps (many years ago)...

Iron
RX has 5-stage pipilene
Iron

"CISC can be microcoded on top of RISC, but typically there is extra hardware to assist with decoding instructions, etc."

? I think most chips are implemented this way nowadays.

@Alaskaman66

 

Basic is used in almost every Micro, just need to find a compiler for it.

Iron

78RPM- Most 8-bit MCUs don;t need pipelines since they are focused on low cost. Most 32-biters do use pipelines however- typically with 3 stages...

Iron

Warren, is Basic used in anything besides Stamp MCU's?

jjrochow- Register files are typically a set of 8 or 16 local registers connects directly to the ALU so you don;t need to go back and forth to main memory (which is slow) to access your variables.

Block oriented cache can be more efficient when main memory is accessed in blocks. That way you don;t go bakc to main memory as often to get the next word.

CISC can be microcoded on top of RISC, but typically there is extra hardware to assist with decoding instructions, etc.

Iron

Slide 13 - One thing I found with CISC was not only were there multiple cycles per instruction, but varying numbers of cycles and varying instruction lengths.  An instruction could be one byte long but take 7 cycles, or might be 3 bytes long and take only 3 cycles.  Very tough to pipeline.  With RISC, you might want to do something really simple (check a zero bit), and then find out you still needed a 32 bit or 64 bit instruction.

Iron

? C is enogh to survive in embedded system or do we need to be proficient in Assembly also 

Iron

I think Asm needed for arcitecture undestanding, almost all can be coded in C with asm inlines in some critical places

Iron

I can't imagine not using interrupts. I hate wait loops and polling.

Robotics - Moter Control, Sensors, Algorithms.

And it's sunny in Southern California!

 

?I have seen out of order execution in some feature sets but haven't needed to deal with one yet. Have you needed to code for a chip using out of order execution?

Iron

?? Warren, I suspect that Pipelines are only supported by higher end MCUs. Is that correct? I suspect most 8-bit MCUs don't offer this feature.

Gold

? Aren't the CISCs microcoded on top of a RISC architecture?
? Why is a block-accessed cache more efficient than one that is not?
? Can you explain the Register File concept?

Dev.khan- One way to get started is to use an evaluation board like Arduino to do some designs. Thats a very easy way to get strated. A great community of support too.

Iron

Thanks Warren. Most informative

 

?How does the CPU know that there is an interrupt and it has to save the context?

I mean, yes there is a hardware line that goes active whenever there is an interrupt, but the when does the CPU start executing it? It may not execute the ISR in the middle of the current instruction that the PC was executing. Does the CPU poll to check whether there is an active interrupt?

Iron

? C is enogh to survive in embedded system or do we need to be profiecient in assembly also

Iron

No questions today? Guess I covered everything!

Iron

? Will you discuss some multicore?

 

I'm getting into this scheme but i can't leave behind the concept of interrupts.

Iron

? Aren't the CISCs microcoded on top of a RISC architecture?
? Why is a block-accessed cache more efficient than one that is not?
? Can you explain the Register File concept?

? Embedded system is very vast from where to start or in another world on which part we should focus

Iron

Thanks Warren and Lauren

Let's do it again tomorrow

Iron

thank you Warren and Lauren

Iron

Thanks Warren and Lauren.

 

 

Iron

Please use a "?" at the beginning of your post if you have a question for me.

Iron

Thanks Warren and Lauren

Iron

Thanks, Warren, Lauren, and Digi-Key

Gold

I had trouble with the posts before but today was the worst.

Iron

good lecture need to do yesterdays to catch up.

Iron

Thank you Warren and Lauren

Iron
thanks Warren and Lauren
Iron

Use interrupts for real-time. Hand coding spaghetti scheduling makes complex software. RTOS and interrupts make for straight forward coding.

About 50% of my posts are not making it through.

Iron

Interrupts for UART and Input Capture

Iron

Dropped posts have been an issue for over a year

 

Iron

I have to post at least twice

 

Iron

We are on slide 16.

Platinum

There are someone who works whith image processing?

Iron

Really disappointed about posting today....have had to enter twice to get a post most times....:(

Iron

We are on slide 15.

Platinum

We are on slide 14.

Platinum

Interrupts used for timing

Iron

Warren, how many instructions are usually in a CISC set vs a RISC instruction set?

Use Interrupt for timer and sensor inforamations

Iron

ports and discrete i/o

Haven't used any interrupts yet, but I could see where they would be necessary in what we plan on doing in the future.

Iron

Yes I use interrupts

Iron

Interrupts very important to avoid loops -- sensor info

Either response of post is slow or my post got lost.

Gold

? Aren't the CISCs microcoded on top of a RISC architecture?

Should be very fast!!!

Iron

I can't imagine not using interrupts. I hate wait loops and polling.

Yes, used mainly for timing and I/O operations.

Iron
use for sensor I/O(ADC operation) and Timer
Iron

Use interrupts in most projects for timers, sometimes for external events. 

Iron

used inerrupts for events

Iron

interrupts are used for event capture, time keeping and return from low power states.

Iron

Yes I use interrupts at zero IO.

Iron

Yes I use interrupt all the time.... for Usart... imput readings... power down... frequent outputs refresh

Iron

Yes, we use interrupts for time-critical processes.

Interrupts very important.  Timers, ADC, serial I/O

sure, interrupts is fundamental to our designs

Iron

sensor event based interrupts

Iron

Interrupts used for wakeup for scheduled action

Iron

i/o events

no polling

Iron

Interrupts are extremely important. Sensor/serial(232,i2c,spi)/timers

Iron

no, in this application now

Use interrrupts, for timing of internal events.

Iron

? Are important (timers, ADC, external).  Looking into the Propeller (multicore).

Iron
Performance. You can always add more mAh.
Iron

Interrupts are very important: For timing and Periferal control.

Iron

Yes on interrupts. HID, memory dumps.

Iron

Have not used interrupts

Iron

use for timers, sensor information, communications

Iron

Interrupts are very important in our design for I/O.

Iron

We are on slide 13.

Platinum

Yes - INTs for Timer, external events etc

 

Iron

use interupts for collecting sensor info

Iron

Interrupts all the time (timers, sensors, i/o, power modes)

Iron

Using interrupts all the time, for sensor and serial IO

 

Iron

interrupts are mainstay of the code design

Iron

Performance....having trouble today with posting :(

Iron

Warren's question was: Do you use interrupts in your designs?

Platinum

usually low power

Iron

depends from target, but if I need very fast procesing then I use FPGAs

Iron

Low powwer is normally more important than performance in my projects.

Iron

Low power - battery supply

Iron

 80% perf / 20% power(Heat specifically)

Iron

Both depending on application, typically for motor control its performance

Iron

@jafar al-jalal - I am not having a problem with audio today, but sometimes it helps to quit the browser and start it over again.

Iron

We are on slide 12.

Platinum

Usually low power. 

 

Iron

Mixed, but favors througput more.

Iron

High speed perform is more importent to our application.

Iron

power first, then performance

Iron

If assembly allows writing a loop that will fit in a cache, does that improve loop performance after a branch, if the entire block of code gets put into the cache?

Performance is more important for my designs.

For my current applications perfomance

Iron

We are on slide 11.

Platinum

high performance

 

Iron

high performance. 

Iron

? Power.... but it's more a mix of the two.

Iron

High performance more important

Iron

Low power - most on battery

 

Iron

Warren's question was: Is high performance or low power more important in your designs? 

Platinum

8-24MHz on AVRs & x51, 70-400MHz on ARM (NXP, Atmel)

 

Iron

The audio keeps stopping

Usually 8-16MHz, 32-48 MHZ going forward.

Iron

? Why is a block-accessed cache more efficient than one that is not?

Main clock: 12.5mhz X 8 - 100mhz cpu clock X 4 50mhz peripheral clock
Iron

About 10 MHz if I can keep it that low.

Iron

Proprietry architecure - aiming for high clock rate yet only 3-level pipe.

Iron

None specific at this time.

Iron

900 MHz? - It's an ARM chip but I'm not currently directly involved

Iron

~8MHz. But planning to try higher rates in the near future.

Iron

Sensor processing, data conversion

Iron

processor speeds typically 8 - 80 MHz

The audio keeps stopping.

 

Iron

Do not have specific clock speed

Iron

Around 40 MHz now and want to 100 Mhz.

Iron

? 8MHZ, 20 MHZ, 32MHZ, 40MHZ, 80MHZ.

Iron

Currently typically run around 10MHz

Iron

typically in sleep and wake to only 1MHz to read sensors

Iron

200MHz CPU Clock Rate

Iron

Warren's question was: What clock rates does you processor run at?

Platinum

Good afternoon, everyone

Iron

temperature table interpolation, data conversion, axis translation

Iron

Slide 8    ; I've been there

motor control and sensor interface

Iron

Signal processing, ADC/DAC, Motor control

Iron

? Can you explain the Register File concept?

We are on slide eight.

Platinum

 AD signal interface, SPI, ethernet, LCD display, keypad control, phone line communication

Iron

Either posting is slow or my last one was lost....do not do this kind of design in my work.

Iron

Duing to high speed requirement I use C embedded assembly to implement function.

Iron

Sensor interface, some external hardware control. Rarely floating point.

Iron

Input, feedback and control algorithm.

Iron

signal conversion

Iron

Robotics - Moter Control, Sensors, Algorithms.

Tracking test result to identify problem in real-time with floating point calculation

Iron

Fof me is a kind of video signal processing with MAC so we do have a interesting in MCU which includeded MAC DSP unit.

Iron

I monitor lots of inputs using interrupts and do motor drive when not servicing interrupts.

Gold

Motor control, process control and different types of sensors

Iron

signal conversion, floating point

Iron

Motor Control, Sensor, Serial Data

Iron

Motor Control, AD sensor interface, I2c, SPI, USB, etc

Iron

Please, how to translate PIPELINE to spanish ?. (MCU point of view).

I have done lots with sensors and actuators - I don't quite see the link to algorithms though

Iron

Am interested in RTOS Scheduling algorithms.

Iron

Motor control actually all sensor and signal conversions.

Iron

thanks for the slide numbers

 

Iron

We are on slide seven.

Platinum

our application is primarily sensor focused

Iron

? motor control, sensor conditioning.

Iron
