What is the main goal for defining RISC-V?
What is the main goal for defining RISC-V?
- To develop an ISA optimized for a specific microarchitecture style
- To create an open ISA freely available to academia and industry (correct)
- To develop an ISA suitable for simulation and binary translation only
- To create a new Instruction Set Architecture (ISA) for academic use only
What was RISC-V originally defined to support?
What was RISC-V originally defined to support?
- Support for education and research in Computer Architecture (correct)
- Support for network security protocols
- Support for software development in embedded systems
- Support for computer hardware manufacturing
Why has RISC-V grown into an open standard and architecture for the industry?
Why has RISC-V grown into an open standard and architecture for the industry?
- Due to its highly restricted and specialized use cases
- Due to its limited availability for academia only
- Because the industry has adopted it as a free standard and open architecture (correct)
- Because it supports only a specific microarchitecture style

Study Notes
- RISC-V is a new Instruction Set Architecture (ISA) that was originally developed for education and research in Computer Architecture, but has since grown into a free standard and open architecture used by industry.
- Goals for defining RISC-V include: a completely open ISA, a real ISA for native hardware implementation, avoidance of over-architecting, support for both 32-bit and 64-bit address spaces, extensive user-level ISA extensions, and a fully virtualizable ISA.
- The RISC-V specification is a software-visible interface to various hardware implementations, divided into two volumes: one for the "base unprivileged" instructions and one for the "classic privileged" features.
- A RISC-V hardware platform may contain one or more RISC-V-compatible cores, other non-RISC-V cores, fixed-function accelerators, physical memory structures, I/O devices, and an interconnect structure.
- A RISC-V core may have additional specialized instruction-set extensions or a coprocessor, which is a unit attached to a RISC-V core that contains additional architectural state and instruction-set extensions and has some limited autonomy.
- The term accelerator refers to a non-programmable fixed-function unit or a core that can operate autonomously.
