New RIOS Lab to expand RISC open-source ecosystem
CS Prof. Emeritus David Patterson, his former graduate student Zhangxi Tan (PhD ’13), and Lin Zhang of the Tsinghua-UC Berkeley Shenzhen Institute (TBSI), have been chosen to co-direct the new RISC-V International Open Source (RIOS) Laboratory, an non-profit research lab launched by the TBSI. RIOS aims to expand and elevate the capabilities of Reduced Instruction Set Computer (RISC) microprocessors. Patterson, who is currently a distinguished engineer at Google, coined the term RISC in the early 1980s to describe a computer architecture that allowed microprocessors to operate far more efficiently with simple, general instructions. Nearly all of the 16 billion microprocessors produced annually are RISC processors.
