Extending RISC-V ISA With a Custom Instruction Set Extension

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 ...

Checking In On The ISA Wars And Its Impact On CPU Architectures

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 ...
