ABSTRACT:
A circuit for parallel-to-serial or serial-to-parallel conversion uses a multi-stage structure for conversion of long data words section-by-section. Each section of the data word corresponds to length/width of the respective registers or latches of the circuit which are successively controlled by an executive sequencer to process the data word in these smaller sections. The section-by-section conversion provides, for a high data rate, a reduction in clock loading and power dissipation.
