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 ...

Most of us will be familiar at some level with the operation of a basic CPU, usually through exposure to microprocessors of the type that find their way into our projects. We can look at its internal ...

Major Chinese chip designer Loongson unveiled LoongArch, its new generation, self-developed computer instruction set, The Xinhua News Agency reports. The Loongson operation system, based on the new ...

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 ...

An Instruction Set Architecture (ISA) defines the software interface through which for example a central processor unit (CPU) is controlled. Unlike early computer systems which didn’t define a ...

In computer science, an instruction set architecture (ISA) is an abstract model of a computer. It’s also referred to as architecture or computer architecture. Moreover, a central processing unit (CPU) ...

The registers inside the CPU, the machine code instruction set, and the ways in which the instructions interact with the registers and status flags are all intertwined. As you may recall, one of my ...
