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.

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 ...

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.

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 ...
