Improved procedure placement for set associative caches

Improved procedure placement for set associative caches
The performance of most embedded systems is critically dependent on the memory hierarchy performance. In particular, higher cache hit rate can provide significant performance boost to an embedded application. Procedure placement is a popular technique that aims to improve instruction cache hit rate by reducing conflicts in the cache through compile/link time reordering of procedures. However, existing procedure placement techniques make reordering decisions based on imprecise conflict information. This imprecision leads to limited and sometimes negative performance gain, specially for set-associative caches. In this paper, we introduce intermediate blocks profile (IBP) to accurately but compactly model cost-benefit of procedure placement for both direct mapped and set associative caches. We propose an efficient algorithm that exploits IBP to place procedures in memory such that cache conflicts are minimized. Experimental results demonstrate that our approach provides substantial impro...
