From the Institute of Computing Technology division of the Chinese Academy of Sciences and Peng Cheng Laboratory comes a high-performance and well-documented RISC-V core called XiangShan. In the Git repository, you’ll find several branches including at least two stable branches: Yanqihu and Nanhu. The currently developed architecture, Kunminghu, is impressive, with a sophisticated instruction fetch […]
We will admit it: mostly when we see a homebrew CPU design on an FPGA, it is a simple design that wouldn’t raise any eyebrows in the 1970s or 1980s. Not so with [Henry Wong’s] design, though. His x86-like design does superscalar out-of-order execution, just like big commercial modern CPUs. Of course [Henry] designs CPU […]
