This paper presents a chipset for a 16/spl times/16 switching node for the distributed banyan network. This chipset enables the use of a larger and much more efficient switching node than was previously available. Very high performance is required of the chips and thus a number of special circuits have been designed to achieve this performance. The chipset resulting from this design consumes low power. The chips have been designed in 1.0 micron CMOS using a mixture of static and dynamic logic. To achieve the speed needed for a larger node, a register file has been employed to store the packet headers on the control chip. It has an area of 3,150/spl times/3,750 micron, and uses 130,000 transistors. The SRAM blocks on the switch chip, which store a bit-slice of the packets, uses 228,600 transistors.
