IBM solved this problem with the introduction of the Instruction Set Architecture (ISA) and the microcode engine in the 60s. Specifically, the launch of the microcoded IBM System/360 ushered in ...

Instruction set architecture is the link between a computer's software and hardware.

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 … ...

We can look at its internal block diagram and get how it works, see the registers and ALU, follow the principles of a von Neumann architecture, and understand that it has an instruction set with ...

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 ...

It has been a long time coming, and it might have been better if this had been done a decade ago. But with a big injection of open source spirit from its acquisition of Red Hat, IBM is finally taking ...

Evaluation methodology/metrics and caveats, instruction set design, advanced pipelining, instruction level parallelism, prediction-based techniques, alternative architectures (VLIW, Vector and SIMD), ...

Arm vs x86: Instruction sets, architecture, and all key differences explained Arm is the top CPU designer for phones, Intel is the big name in PCs. Both make processors, but what is the difference?

A new instruction set architecture from China's Loongson, which the company claims is fully made in China, could be a new open-source ISA.

Why it matters: Intel is gearing up for what the company considers the "next major step" in the evolution of the original x86 instruction set architecture (ISA). The Santa Clara corporation is ...
