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 ...

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 ...

Arm has enabled custom instructions for embedded centralized processing units (CPUs) to give chip makers more flexibility in a changing world. The new custom instructions will enable partners — who ...

Forward-looking: After being beaten by AMD in introducing the first, truly 64-bit instruction set in the x86 CPU world, Intel is now trying to get ahead of its historical competitor by working on a ...
