An asynchronous interconnect architecture for device security enhancement

We present a new style of long-distance, on-chip interconnect, based loosely on the asynchronous GasP architecture. It has a number of advantages over conventional designs, the most prominent being security enhancements, a reduction in the number of wires required, no need for clock distribution or packetization, and ease of composition. We give some sample throughput and latency figures from simulation on a 0.18μm technology and show that it is viable for use with modern interconnect requirements, is of low complexity and has a lower area requirement than parallel interconnect over distances as short as 1 mm.
