Abstract
The present invention provides a parallel pulse code modulation system enabling the independent control of a plurality of groups of one or more electronic devices. A memory unit receives control data from an external source, and a multiplexer connected to the memory unit receives control data therefrom and organizes it into a serial data stream. A shift register connected to the multiplexer receives the serial data stream and translates groups of data into parallel data stream output, representing control parameters for a particular group of one or more electronic devices. A latch connected to the shift register and to the groups of electronic devices receives each parallel data stream output and sends a particular parallel data stream output to a corresponding group electronic devices. A logic sequencer provides sequencing and timing signals to the memory unit, the multiplexer, the shift register and the latch.
