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 ...

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 ...

Back in the early days of computing, manufacturers didn’t build a whole line of software-compatible computer systems where each system was aimed at a different price/performance point. Instead, each ...

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 ...

This paper describes the design and implementation of a version of the 8051 microcontroller, one of the most commercially used microcontrollers in FPGA with reconfigurable instruction set.

There’s always some debate around what style of architecture is best for certain computing applications, with some on the RISC side citing performance per watt and some on the CISC side citing ...
