Abstract-To avoid data cache trashing between heapallocated data and other data areas, a distinct object cache has been proposed for embedded real-time Java processors. This object cache uses high associativity in order to statically track different object pointers for worst-case execution-time analysis. However, before implementing such an object cache, an empirical analysis of different organization forms is needed. We use a cross-profiling technique based on aspect-oriented programming in order to evaluate different object cache organizations with standard Java benchmarks. From the evaluation we conclude that field access exhibits some temporal locality, but almost no spatial locality. Therefore, filling long cache lines on a miss just introduces a high miss penalty without increasing the hit rate enough to make up for the increased miss penalty. For an object cache, it is more efficient to fill individual words within the cache line on a miss.

“…The object layout is handle based and the cache line is addressed with a combination of the object reference (called object id) and part of the offset within the object. The main motivation of the object cache mode is in-cache garbage collection of the youngest generation [16].…”

Abstract-Static cache analysis for data allocated on the heap is practically impossible for standard data caches. We propose a distinct object cache for heap allocated data. The cache is highly associative to track symbolic object addresses in the static analysis. Cache lines are organized to hold single objects and individual fields are loaded on a miss. This cache organization is statically analyzable and improves the performance. In this paper we present the design and implementation of the object cache in a uniprocessor and chipmultiprocessor version of the Java processor JOP.
