Abstract: A computing system includes: an instruction dispatch module configured to receive an address stream; a prefetch module, coupled to the instruction dispatch module, configured to: train to concurrently detect a single-stride pattern or a multi-stride pattern from the address stream, speculatively fetch a program data based on the single-stride pattern or the multi-stride pattern, and continue to train for the single-stride pattern with a larger value for a stride count or for the multi-stride pattern.

Abstract translation: 计算系统包括：指令调度模块，被配置为接收地址流; 耦合到所述指令调度模块的预取模块，被配置为：训练从所述地址流同时检测单步模式或多步式模式，基于所述单步模式或所述多步式模式推测性地获取程序数据， 并且继续训练具有更大的步幅计数或多步式模式的单步式模式。
