We investigate two scalar coprocessors for accelerating the ITU-T G723.1 and G729A speech coders. Architecture space exploration indicates up to 72% reduction in the total number of instructions executed through the introduction of custom instructions and small changes to the C reference code. The accelerators are designed to be attached to a configurable embedded RISC CPU where they make use of the host register file and load/store infrastructure.
