Because of time difference ( India ) I was unable to participate immediately.
It was an excellennt presentation. I am a hardware engineer and may be I understand the logic behind the software. I cannot go into codes directly. I am looking for the design of Microcontroller for Motor Control applications in Automative applications. The temperature within the enclosure of this system to be planned is 180 deg Celcius. The competitors use ST Micrpcontroller L9805. The requirement is very precise control of the motor speed with position feedback, appropriate acceleration and deceleration. Uses CAN bus Communication from Engine Unit.
Mr Warren, I would appreciate if you can suggest a suitable microcontroller to work at high temperature, automative applications very reliably. Where can I get some reference designs.
rshakle- On the prices for the tools, it is best to check out the vendors web sites (or at Digi-Key) since the prices do change. Look for special deals too- sometimes if you attend a training you can get a big discount!
@sherlock- Since the SoC FPGAs use dedicated CPUs the timing is fixed. If you access an external (in fabric) peripheral a dedicated bus interface is used so timing isn't changed. Only latency will be different for the peripheral depending on place and route results...
One question, if it is possible that the SoC core (MCU) timing will be changed after some self-made IP were added and recompiled design? such as NIOSII core it is comes from normal logic cell not an integreted MCU core? I am just interesting in here actually I don't met this problem. If they will happen on high speed possible?
@DBarth- Vivado was a new design so initially there were some issues but they have gradually been addressed. That might be the source of the negative feedback. It can be a copmplex tool, so someone who just wants it simple might find id daunting...
@Seaguard- The $30 or so kits are for FPGA only boards (not SoC FPGAs) but you can get started with them to learn about FPGAs. You can use a soft MCU however (implemented in fabric) to test out the MCU tool flow too!
??Many of the designs I work with utilize a separate FPGA and MCU - and oftentimes the MCU alone meet my design needs. Are the shared resources / speed the primary reason to utilize a combined MCU/FPGA?
?$30 Eval Board? ?Is that for a combined FPGA/MCU? ?If so, any specific examples? I've seen FPGA only or MCU only for around $30. Lowest combined that I've found is the Micro Semi A2F-EVAL-KIT-2 at $123.25 plus $79.75 for daughter card (not in stock). It seems to be cheaper at the eval level to start with separate MCU and FPGA boards.
I've had vary varying experiences with quality of eval or dev kit hardware+software combination, meaning, some vendors are much much better than others about supplying you with a complete bottom-to-top toolchain (while others deliver general hardware along with a barebones software toolchain -- like, a C compiler with...maybe libc if you're lucky, and then maybe nothing else).
So if anyone's listening, providing a fully-useful set of tools for working on real projects out of the box makes dev/ev kits go so, so much further.
I'd imagine it depends on the type of work you're engaged in...generally speaking, for me, prototyping things quickly such that you can show someone a working proof of concept in short order can be extremely valuable
Did a little simulation in the past, but found it to be more trouble than it was worth in most of our applications (SHARC DSPs. Easier, in my cases, to just write/debug the code directly. Not sure that will be the case with FPGAs.
Somewhere in between...software tends to be easier [for me] to utilize to rapidly prototype (or fully develop) when possible (particularly where well-designed high-level libraries are part of a given ecosystem).
