Have played with most of these except the Hitachi, first processor I played with was the RCA scamp, built my first digital computer based on a Motorola 6801. Have put a lot of products in the field with 8048, 8051, 6800 and PIC based circuits. A basic slurpie machine has a 6811, and up to 5 PICs just to give you a frozen beverage.
Great material to show the shift from 8-Bit to 32-Bit in Today's Microcontroller worls, and the best part is with Today's process technologies the cost of a small entrey Level 32 Bit Micro is the same if not even lower than an 8 Bit Micro.
I have worked with some of there processsors, primarily as a graduate teaching assistant. I taught laboratories using the 8085, which was a new device at the time, and also used the 6800 a little bit. As an undergraduate I remember entering programs into an 8080 system with toggle switches. And don't forget the 6502!
I wonder if the idea is for hardware mftrs just to team up with a C/C+ or Java compiler outfit and bring out a toolchain and performance metrics and we just base our decision on the cost/metrics (and don't care anymore whether is is a dual-core chip, FPGA uCs chip or ultrafast 2-bit RISC micro, whatever).
Are you covering the architecure level info of CORTEX MO processor in upcoming letcures? Curious to know on the transistor level design practice of the architecure like static core with dynamic logic core
@jl: I think the real significance is that the C compiler will generate instruction sequences similar to what is being presented, so that two processors at identical clock speeds take hugely different times to do the exact same line of C source code, even after the compiler does every clever thing it can to optimize.
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
