Abstract: As processor performance increases, there is a corresponding increase in the demands on the memory system, including caches. Research papers have proposed partitioning the cache into instruction/data, temporal/non-temporal, and/or stack/non-stack regions. Each of these designs can improve performance by constructing two separate structures which can be probed in parallel while reducing contention. In this paper, we propose a new memory organization that partitions data references into stack and non-stack regions. Non-stack references are routed to a conventional cache. Stack references, on the other hand, are shown to have several characteristics that can be leveraged to improve performance using a less conventional storage organization. This paper enumerates those characteristics and proposes a new microarchitectural feature, the stack value file (SVF), which exploits them to improve instruction-level parallelism, reduce stack access latencies, reduce demand on the first-level cache, and reduce data bus traffic. Our results show that the SVF can improve execution performance by 29 to 65% while reducing overhead traffic for the stack region by many orders of magnitude over cache structures of the same size.
