An instruction set architecture (ISA) defines the set of basic operations a computer must support. This includes the functional definition of operations and precise descriptions of how to invoke and ...

In computer science, an instruction set architecture (ISA) is an abstract model of a computer. It’s also referred to as architecture or computer architecture. Moreover, a central processing unit (CPU) ...

If instruction sets didn't matter, processors would be cheaper and designers would have more options. That's why one startup's efforts are so intriguing. Every microprocessor is different, in part ...

The registers inside the CPU, the machine code instruction set, and the ways in which the instructions interact with the registers and status flags are all intertwined. As you may recall, one of my ...

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 ...

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 a ...

First and foremost, RISC-V is a modular, open-source, instruction set definition and nothing more. RISC-V as an ecosystem is much more. The instruction set provides the encoding and semantics, but it ...
