A digital synthesizer using Tau (time) synthesis. The digital Tau synthesizer employs a time accumulator to accumulate reference periods at the rising edge of each reference clock signal. The accumulator is then constrained to count reference pulses modulo Tp (the programmed period). The accumulated time is then used to gate out the pulse that occurs just before the desired time and to set up a delay line with the appropriate values for this delay.

A pipelined programmable digital pulse delay system (10) that is capable of processing multiple input pulses simultaneously, each with a unique programmed delay value, includes a plurality of pulse delay units (12, 14, 16), a plurality of buffer registers (18, 20, 22, 24), and a commutator unit 26. The buffer registers (18, 20, 22, 24) each store a delay control word corresponding to a single pulse currently being processed in the system (10). The plurality of pulse delay units (12, 14, 16) each reference a corresponding buffer register (18, 20, 22, 24) for an appropriate delay control value when a particular pulse is about to be received by the pulse delay unit. After the pulse has passed an operative point in the pulse delay unit, the unit then retrieves a delay control value from another buffer register (18, 20, 22, 24) for use with a next input pulse. Thus, pipelined operation is achieved in the system (10).
