DSP datapath synthesis eliminating global interconnect

CASS (column architecture synthesis system) is a behavioral high level synthesis system for DSP applications. It uses a column based target architecture and in-the-cell routing to produce compact layout which eliminates the need for global wiring. This is achieved using bit-sliced cells which butt together to produce the data path. A description of the architecture and algorithms which produce the datapath is given. It is also shown that this approach gives large area savings when compared to a conventional system
