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, ...

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 ...

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 ...

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 ...

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 ...

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 ...

Chinese chip maker Loongson used to make processors based on MIPS architecture, but MIPS isn’t what it used to be and the company that developed the technology has even pivoted to making chips using ...

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 ...

If instruction sets didn't matter, processors would be cheaper and designers would have more options. That's why one startup's efforts are so intriguing. Every microprocessor is different, in part ...

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 ...
