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 ...

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 ...

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.

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 ...

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 ...

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.

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 ...
