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) ...

First, architecture basics are detailed with information on the register sets, data types, and memory and instruction formats. Next, instruction set extensions are detailed, which include Intel® ...

When developing software for small microcontrollers, it is common to use assembly language in the final product. But there is still much value in prototyping the software and its algortihms in C. Here ...

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 ...

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 ...

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 ...

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 ...
