The authors present a self-timed architectural
interface design for VLSI CMOS integrated circuit systems. The
interface follows a two-cycle self-timed bundled data protocol and
nearly doubles the input/output (I/O) bandwidth for wide bus VLSI
interprocessor communication by simultaneously sending and receiving
data over the same wires. A constant overhead of four control wires
is incurred over the synchronous approach proposed by K. Lam et al.
(1990), as well as a decaying area penalty for increasing bus
widths. This type of self-timed bundled interface can prove
attractive for applications where global synchronization is
difficult to achieve. The interface has been simulated for a 16-b
wide bus using a quasi-analog mixed-signal Verilog approach.
