CPUs that process 128 bits as a single unit, compared to 8, 16, 32 or 64 bits. There are no 128-bit CPUs on the market and there may never be because there is no practical reason for doubling the ...

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 ...

Hi everyone! Have you heard of the brand new 8-bit computer built from (mostly) off-the-shelf parts called Commander X16 made by a team of people under The 8-Bit Guy (David Murray)? If so what are ...
