# openLA500
## 前言
openLA500是一款实现了龙芯架构32位精简版指令集(loongarch32r)的处理器核。其结构为单发射五级流水,分为取指、译码、执行、访存、写回五个流水级。并且含有两路组相连结构的指令和数据cache;32项tlb;以及简易的分支预测器。此外,处理器核对外为AXI接口,容易集成。
OpenLA500已经过流片验证,.13工艺下频率为100M,dhrystone,coremark分数分别为0.78 DMIPS/MHz(指令数有点高),2.75 coremark/Mhz。软件方面,uboot、linux 5.14、ucore、rt-thread等常用工具及内核已完成对openLA500的适配。
