ABSTRACT:
A data processing system. The data processing system includes a time division multiplexed (TDM) bus and a plurality of system components coupled to the TDM data bus. A memory stores a table of allocation entries. Each allocation entry indicates which one of the plurality of system components, if any, to be allocated a corresponding bandwidth unit (BU), wherein each BU comprises a contiguous block of TDM timeslots. An allocation control circuit is coupled to the system components and the memory for accessing the allocation table and allocating BUs to the system components on a BU-by-BU basis so that the allocation control circuit operates at a slower speed than the TDM data bus.
