Video gamers know about cheat codes, but assembly language programmers are often in search of undocumented instructions. One way to find them is to map out all of a CPU’s opcodes and where there are ...

I'm still busily beavering away on the idea of my Heath Robinson Rube Goldberg mixed-technology computer (relays, vacuum tubes, transistors, fluidic logic, etc.). As you'll see if you visit the above ...

x86, the mainstream instruction set architecture for PC CPUs, originated from the Intel 8086 processor and has been in use for 46 years. Technology blog Hackaday claims that x86 will be extinct in the ...

Single-instruction, multiple-data (SIMD) instructions that can process multiple data with one instruction greatly contribute to the speedup of CPU operation. However, since SIMD instructions require a ...

RISC-V processors are quickly becoming mainstream. The open standard means freedom for many developers, but success depends on the development of a support ecosystem around RISC-V. Industry ...
