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 ...

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.

A technical paper titled “Energy-Efficient Exposed Datapath Architecture With a RISC-V Instruction Set Mode” was published by researchers at Tampere University. Abstract: “Transport triggered ...

An instruction set architecture, or ISA, defines the language in which a central processing unit expresses computations. The “words” of this language are instructions, ...

Intel Corp. and Advanced Micro Devices Inc. today launched an industry group dedicated to improving the x86 instruction set architecture.. Besides the two chipmakers, the consortium, announced at ...

The instruction set provides the encoding and semantics, but it doesn't specify how it's implemented, leading to the plethora of RISC-V cores, chips, and boards.

In a nutshell: Intel has unveiled the latest revision of its pared-down X86S instruction set architecture. Version 1.2 takes the trimming trend further by axing multiple 16-bit and 32-bit features.
