ABSTRACT
Many high performance DSP systems such as HiFi audio, telecommunication and
image processing can be implemented in VLSI. The design complexity and the
large number of architectural alternatives necessitates the automation of
architecture design. Architectural synthesis makes the design task less
error prone, allows fast prototyping, explores a wide architecture space,
facilitates design changes, and can result in more efficient hardware. In
this talk, the state of the art architecture synthesis tools will be
overviewed. A high performance architectural synthesis tool for DSP,
SPAID, will be presented. SPAID synthesizes processors with synchronous
multiple bus data path architectures and asynchronous interfaces from
signal flow graph algorithm specification. The processors synthesized by
SPAID are suited for multiprocessor implementation of DSP systems.
The advantages of SPAID synthesis methodology over others will be
demonstrated through benchmark examples. The use of SPAID in the design of
HiFi stereo filter DSP chip will also be presented.
