Electronic Circuit Wherein an Asynchronous Delay is Realized

摘要

The electronic circuit contains a basic delay circuit ( 14 ). A delay is realized by activating the same basic delay circuit ( 14 ) a plurality of times in response to a single start signal before generating a response to that start signal. A control circuit ( 12 ) receives a start signal and an outputs a response. The control circuit ( 12 ) causes a series of signals to be passed through the delay circuit ( 14 ), the series starting at a time that is time-continuously triggered by the start signal. Each successive signal in the series starts after a preceding signal has emerged from the delay circuit ( 12 ) and the series being terminated after a controlled number of more than one signal has been passed. The control circuit ( 12 ) supplies the response upon termination of the series. In one embodiment the series is realized by means of a handshake sequencing circuit ( 120 ) that generates a series of successive handshake transactions.
