Conventional register file architectures cannot optimally exploit temporal locality in data references due to their limited capacity and static encoding of register addresses in instructions. In conventional embedded architectures, the register file capacity cannot be increased without resorting to longer instruction words. Similarly, loop unrolling is often required to exploit locality in the register file accesses across iterations because naming registers statically is inflexible. Both optimizations lead to significant code size increases, which is undesirable in embedded systems.
