Instruction Set Architecture (ISA) is a set of instructions defined for the processor’s architecture. These are the instructions that the processor understands. It defines the hardware and software ...

The nRF51 Series SoCs is a family of low power Bluetooth chips from Nordic Semiconductor that is based on ARM Cortex cores. The nRF51822 has the Cortex M0 core and is used in a lot of products. [Loren ...

This proposed instruction set is intended to run on both virtual and physical incarnations of the 4-Bit HRRG Computer As you may recall, my chum Chewy is interested in designing and building a 4-bit ...

When developing software for small microcontrollers, it is common to use assembly language in the final product. But there is still much value in prototyping the software and its algortihms in C. Here ...

It has been a long time coming, and it might have been better if this had been done a decade ago. But with a big injection of open source spirit from its acquisition of Red Hat, IBM is finally taking ...

Introduced in 1998, 3DNow! was AMD's answer to the growing multimedia demands being placed on the K6-2 silicon of the day. Today AMD has announced that the instruction set is being deprecated. AMD ...

If instruction sets didn't matter, processors would be cheaper and designers would have more options. That's why one startup's efforts are so intriguing. Every microprocessor is different, in part ...

The dispute between Qualcomm and Arm has escalated with the latter canceling Qualcomm’s ability to use the instruction set for designing chips. According to Bloomberg today, Arm is “canceling a ...

I suppose the holy grail would be to bootstrap your custom CPU into a full-blown Linux system. That’s a big enough job that I haven’t done it. Although you might be more productive than I am, you ...
