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 ...

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 ...

There’s always some debate around what style of architecture is best for certain computing applications, with some on the RISC side citing performance per watt and some on the CISC side citing ...

Cortus, which licenses small 32-bit cores, has upgraded its instruction set and launched two new cores which use the new one. Why upgrade? “Embedded applications have got more complex,” replies Cortus ...

China-based CPU designer Loongson Zongke Technology has pledged to build a homegrown CPU instruction ecosystem independent of Wintel and Android-ARM, and all its products will switch to the ...

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 ...

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 ...

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 ...
