GPU中的流式多处理器（SM）架构设计Stream Multi-processor (SM) Architecture in GPU Design
➀ 流式多处理器（SM）是GPU的核心模块，执行整个Kernel Grid。➁ SM包括SIMT前端和SIMD后端，处理指令分为六个阶段：取指、译码、发射、操作数传送、执行与写回。➂ SM支持指令级并行但不支持乱序执行，每个Warp以SIMD方式执行相同指令。➀ The Stream Multi-processor (SM) is the core module of the GPU, executing the entire Kernel Grid. ➁ SM consists of a SIMT front end and a SIMD back end, processing instructions in six stages: fetch, decode, issue, operand delivery, execute, and write back. ➂ SM supports instruction-level parallelism but not out-of-order execution, with each Warp executing the same instruction in SIMD mode.
