ABSTRACT:
An apparatus for and method of efficiently providing a modular dayclock within a data processing system. This is accomplished by dividing the dayclock hardware into a number of dayclock modules configured to operate in a bit serial fashion. This allows the dayclock to accommodate a variety of dayclock word widths by simply varying the number of dayclock modules provided. Further, since the dayclock may operate serially, rather than in parallel fashion, the number of dayclock module I/O's and board route channels may be substantially reduced. Finally, all control logic may be provided directly in the dayclock modules, thereby eliminating the need for a central dayclock controller.
