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 ...

In semiconductors, architecture refers to the instruction set architecture (ISA), a detailed set of rules and specifications governing how a chip processes data and executes instructions ...

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.

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?

All CPUs have some sort of Instruction Set Architecture (ISA), and whether it’s x86, ARM, SPARC, Power, or Alpha. Different ISAs can are faster at some tasks, and slower at others.

Rather than extend its 32-bit instruction set, Arm offers a clean 64-bit implementation. To accomplish this, the ARMv8 architecture uses two execution states, AArch32 and AArch64.

Open source software is popular – for operating systems as well as for office programs. But can this idea also work with hardware? We interviewed Rick O'Connor, Executive Director of the RISC-V ...

This week at The Linux Foundation Open Source Summit, IBM announced it is opening the POWER Instruction Set Architecture (ISA). "The opening of the Power ISA, an architecture with a long and ...
