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, ...

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 ...

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 ...

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 ...

Most of us will be familiar at some level with the operation of a basic CPU, usually through exposure to microprocessors of the type that find their way into our projects. We can look at its internal ...

3DNow! was introduced in 1998 as a part of AMD's K6-2 family of processors to help boost the performance of certain intensive applications. However, the company has announced that it will be retiring ...

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 ...
