E. Grass et S. Jones, ACTIVITY-MONITORING COMPLETION-DETECTION (AMCD) - A NEW APPROACH TO ACHIEVE SELF-TIMING, Electronics Letters, 32(2), 1996, pp. 86-88
A new method for designing asynchronous circuits is described. It uses
additional circuitry to monitor the activity of internal nodes. When
all transitions have halted, a completion signal is generated. Details
of the circuit and design methodology are given. The proposed approac
h results in faster operation than synchronous circuits, with only a s
mall circuit overhead incurred.
