A microprogrammable VLSI routing controller for HARTS

The design and implementation of a VLSI routing controller for use in the Hexagonal Architecture for Real-Time Systems (HARTS), which is currently being built, are presented. The routing controller is a microprogrammed unit designed to function as an intelligent front-end interface for the interconnection network. Unlike other routine controllers known to date, this routing controller allows for the flexibility to investigate several low-level routing algorithms by downloading the appropriate microcode into the routing controller. The design was carried out using the combination of Seattle Silicon Technology's silicon compiler and Mentor Graphic's schematic capture and simulation tools. The implementation is targeted for a 64-pin package using a 1.2- mu m CMOS process.<
