Abstract
An asynchronous pulse domain to synchronous digital domain converter for converting pulse domain signals in an input asynchronous pulse domain data stream to synchronous digital domain signals in a data output stream. The converter comprises a plurality of counters arranged in a ring configuration with only one counter in the ring being responsive at any given time to positive and negative going pulses in the input asynchronous pulse domain data stream, each counter, when so responsive, counting a number of time units between either (i) a positive going pulse and an immediately following negative going pulse or (ii) a negative going pulse and an immediately following positive going pulse, the counts of the counters when so responsive being synchronously converted to synchronous digital domain signals in the data output stream. The disclosed asynchronous pulse domain to synchronous digital domain converter can be used with spike domain signals if desired.
