ASYNCHRONOUS CONTROL SIGNAL GENERATING APPARATUS

摘要

Apparatus for asynchronously generating control signals (CONTROL) is disclosed including a plurality of sources (5) of asynchronous data signals and a plurality of data processing channels (10, 14), each processing one of the data signals in response to a control signal (CONTROL). Each of a plurality of parameter determining circuits (10, 16) produces a signal (COMPLEXITY) representing a parameter of one of the data signals. A data sampler (30) samples the signals (COMPLEXITY) from all of parameter determining circuits (10, 16) substantially simultaneously at predetermined sampling time intervals. A control signal generator (30) generates control signals (CONTROL) for the data processing channels (10, 14) having values based on the sampled parameter representative signals (COMPLEXITY) and the preceding sampling time interval.
