Study Notes
RISC-V Overview
- RISC-V was originally defined to be a free and open ISA (Instruction Set Architecture) enabling a new era of innovation and collaboration.
- The primary goal for defining RISC-V is to create a modern, modular, and extensible ISA that is suitable for a wide range of applications.
RISC-V Characteristics
- RISC-V is distinguished from other ISAs in terms of hardware implementation, allowing it to be open-source, free, and customizable.
- The RISC-V ISA specification avoids defining as much as possible, allowing for maximum flexibility and customizability.
- RISC-V is suitable for a wide range of applications, from small embedded microcontrollers to large server systems.
RISC-V ISA
- The RISC-V ISA is divided into a small base integer ISA and optional standard extensions, such as floating-point, vectored, and compressed instructions.
- The RISC-V ISA supports various address space variants for applications and hardware implementations, including 32-bit and 64-bit address spaces.
RISC-V Hardware Platform
- A RISC-V hardware platform contains RISC-V-compatible processing cores, as well as additional units such as accelerators, and coprocessors.
- A unit attached to a RISC-V core, mostly sequenced by a RISC-V instruction stream, but containing additional architectural state and instruction-set extensions, is referred to as a coprocessor.
- An accelerator in a RISC-V hardware platform refers to a unit that performs specific tasks, such as encryption, compression, or graphics processing.
RISC-V Features
- Optional variable-length instructions in the RISC-V ISA support dynamic compression of instructions.
