In multicore processor systems, last-level caches (LLCs) play a crucial role in reducing
system energy by i) filtering out expensive accesses to main memory and ii) reducing the …

Cache memories play a critical role in bridging the latency, bandwidth, and energy gaps
between cores and off-chip memory. However, caches frequently consume a significant …

Cache compression seeks the benefits of a larger cache with the area and power of a
smaller cache. Ideally, a compressed cache increases effective capacity by tightly …

Cache compression has largely focused on improving single-stream application
performance. In contrast, this work proposes utilizing cache compression to improve …

The effectiveness of a compressed cache depends on three features: i) the compression
scheme, ii) the compaction scheme, and iii) the cache layout of the compressed cache …

Modern processors use two or more levels ofcache memories to bridge the rising disparity
betweenprocessor and memory speeds. Compression canimprove cache performance by …

Compression is seen as a simple technique to increase the effective cache capacity.
Unfortunately, compression techniques either incur tag area overheads or restrict cache …

Cache compression is a promising technique to increase on-chip cache capacity and to
decrease on-chip and off-chip bandwidth usage. Unfortunately, directly applying well-known …

In this paper, we identify a previously untapped source of compressibility in cache working
sets: clusters of cachelines that are similar, but not identical, to one another. To compress …

The memory wall has motivated many enhancements to cache management policies aimed
at reducing misses. Cache compression has been proposed to increase effective cache …
