Abstract

SPAID, a design tool that maps digital signal processing (DSP) algorithms into a multibus VLSI architecture is discussed. Algorithm structure, design style of functional units (FU), and parallelism of the architecture are all explored in the design space. SPAID supports pipelined and multicycle functional units. The synthesized processor is a self-timed element externally, while it is internally synchronous. SPAID explores a wider space, and produces better solutions compared with existing synthesis systems on an elliptic filter benchmark design example. A multibus multifunctional unit processor matched to the implemented algorithm is synthesized using SPAID.<>
