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 ...

Creating Domain Specific Processors Using Custom RISC-V ISA Instructions

When System-on-Chip (SoC) developers include processors in their designs, they face choices in solving their computational challenges. Complex SoCs will usually have a variety of processor cores ...
