本文主要介绍OpenBLAS的RISC-V Vector extension(v 扩展/向量扩展)两个版本:RISC-V Vector extension 0.7.1.和RISC-V Vector extension 1.0.分别在SG2042和K1上的验证。 首先是准备了一台x86_64的设备作交叉编译准备,使用gcc 13.3.0,工具链为:Xuantie-900系列工具链,具体版本
得到更少但是更长的向量寄存器,called "vector register group" ,运行作为单个向量,但是被运行的向量名字必须是偶数名字,例如LMUL=2(v0, v2,..), LMUL = 4(v0, v4,...)。 被用来 1) accomodate mixed-width operations, and/or 2) to increase efficiency by using longer vector when fewer separate ...
Input IR to VPReciple IR:通过合法性分析 + TTI 对应的目标平台后端提供的代价模型获取最优VF,并将结果存储到VPlan中,完成首次VPlan model 的构建,此时无需更新控制流。 VPlan-to-VPlan Transform Pipeline:在获取VPlan 之后,针对一些场景做优化,例如冗余Recipe 删除、简化Vector Region 实现(循环条件或者循环归...
