XiangShan 数据预取器架构代码解读
Created2026-06-11|cpucacheprefetchdata-pf
XiangShan Prefetcher RTL 实现核心设计思想是: 上层预取器可以跨层级”指示”下层预取(L1 可以让 L2 预取,L1 可以让 L3 预取),但这种跨层指示走的是 专用旁路通道(sideband,BundleBridge),而不是 TileLink 缓存一致性总线上的 Hint 报文; 每个预取请求都携带”来源标识”(pfSource / MemReqSource),使得请求在跨层传递、在下层流水线处理、以及在性能统计时都能追溯到是哪一级、哪一个预取器发起的; 预取深度按层级递增:越靠近核心的层级(L1)预取得越”近”(lookahead 小),越远的层级(L2/L3)预取得越”远”(lookahead 大),以匹配各级 miss 延迟差异 各层级使用的预取器: 层级 算法 说明 L1 D-Cache Stride、Stream、SMS(Spatial Memory Streaming) Stride/Stream 由 L1Prefetcher 统一管理;SMS 是独立模块 L2(coupledL2) BOP...
