香山开源高性能RISC V处理器敏捷设计实践

Agile Development Practice of Xiangshan Open-source High-performance RISC V Processor

2019年,在中国科学院支持下,由中国科学院计算技术研究所牵头发起“香山”高性能开源RISC V处理器项目,研发出目前国际上性能最高的开源高性能RISC V处理器核“香山”,在开源项目托管平台GitHub上获得超过3000个星标,形成360多个分支,成为国际上广受关注的开源硬件项目之一,得到国内外企业的支持。2021年6月22日,“香山”开源高性能RISC V处理器在首届RISC V中国峰会上亮相,引起了各界的广泛关注。本文根据第二届RISC V中国峰会的主会报告“香山开源高性能RISC V处理器敏捷设计实践”整理而成,分享香山过去一年的总体进展。

In 2019,with the support of Chinese Academy of Sciences,the Institute of Computing Technology led the Xiangshan high-performance open-source RISC V processor project.We develop the highest performance open-source RISC V processor core Xiangshan in the world for now.The project host in GitHub has gained more than 3000 stars and 360 forks.It has become one of the most popular open-source hardware projects globally and has been actively supported by domestic and foreign companies.On June 22,2021,the Xiangshan processor made its debut at the first RISC V China Summit,which attracted widespread attention.This paper is based on the report in the 2nd RISC V China Summit"Agile Design Practice of Xiangshan Open-Source High Performance RISC V Processor".We will share the overall progress of Xiangshan in the past year.
