Implementing a STARI chip

STARI is a high-speed signaling technique that uses both synchronous and self-timed circuits. To demonstrate STARI, a chip has been fabricated using the MOSIS 2 CMOS process. In a simple test xture, it operates at data rates of 120 Mbits/sec over a pair of wires. Because STARI uses both synchronous and selftimed circuits, it provides an opportunity to compare these two design methods. The synchronous circuits of the STARI chip achieve rates of operation two to three times those of the self-timed circuits. However, the self-timed FIFO in the receiver provides robust compensation for clock skew that could not be achieved with synchronous circuitry alone. Thus, the STARI chip demonstrates advantages of combining these two design techniques.
