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) ...

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 ...

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 ...

RISC-V ISA (Instruction Set Architecture) is designed in a modular way. It means that the ISA has several groups of instructions (ISA extensions) that can be enabled or disabled as needed. This allows ...

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 ...

The open-source RISC-V instruction set architecture (ISA) continues to gain momentum, but the flexibility of RISC-V creates a problem—how do you know if a RISC-V implementation fits basic standards ...

Introduced in 1998, 3DNow! was AMD's answer to the growing multimedia demands being placed on the K6-2 silicon of the day. Today AMD has announced that the instruction set is being deprecated. AMD ...

There’s always some debate around what style of architecture is best for certain computing applications, with some on the RISC side citing performance per watt and some on the CISC side citing ...
