Hello all, I have a question regarding CPU instruction sets. I have heard that the aging x86 instruction set is holding back progress, so to speak. So I was thinking about what would make a better, ...

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 ...

The S5000 software-configurable processor family combines the flexibility of the compilable Tensilica Xtensa RISC processor core and the programmable Stretch instruction-set extension fabric (ISEF) to ...

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 ...

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 ...

The Android operating system is built to run on three different types of processor architecture: Arm, Intel x86, and MIPS. The former is today’s ubiquitous architecture after Intel abandoned its ...

This paper presents an instruction set simulator of a 32-bit CPU and explains its use in embedded software development. Interaction of the ISS with transaction level model of a complex peripheral ...

There was a time when owning a computer meant you probably knew most or all of the instructions it could execute. Your modern PC, though, has a lot of instructions, many of them meant for specialized ...

I suppose the holy grail would be to bootstrap your custom CPU into a full-blown Linux system. That’s a big enough job that I haven’t done it. Although you might be more productive than I am, you ...
