Abstract

Indirect memory accesses have irregular access patterns and concomitantly poor spatial locality. To address this problem, we propose the Array Tracking Prefetcher which tracks array-based indirect memory accesses using a novel combination of software and hardware. Our results show that ATP yields average speedup of 1.60 over the baseline single-core without prefetching. By contrast, the speedup for conventional software and hardware-based prefetching, is 1.49 and 1.16, respectively. For four-cores, the average speedups for ATP, software, and hardware are 1.49, 1.38, and 1.11, respectively.
