Stream Register Files with Indexed Access

Many current programmable architectures designed to exploit data parallelism require computation to be structured to operate on sequentially accessed vectors or streams of data. Applications with less regular data access patterns perform sub-optimally on such architectures. This paper presents a register file for streams (SRF) that allows arbitrary, indexed accesses. Compared to sequential SRF access, indexed access captures more temporal locality, reduces data replication in the SRF, and provides efficient support for certain types of complex access patterns. Our simulations show that indexed
