Abstract:
1. A system comprising: a sample request interface configured to initiate the transfer of slots onto a cyclic request bus, to receive filled slots indicating scanline requests from a plurality of filtering units, to store the scanline requests in request buffers corresponding to the filtering units, and to withhold the initiation of the transfer of slots for a first of the filtering units while the corresponding request buffer is full; a plurality of arbiters, wherein each arbiter is configured to read the request buffers and to arbitrate among scanline requests addressing a corresponding memory group, resulting in burst requests being stored in corresponding forwarder buffers; and a plurality of forwarder buffers, wherein each forwarder buffer is configured to read a burst request from the corresponding forwarder buffer and to transfer the burst request to one or more scheduling units to induce transfer of a corresponding sample burst to a requesting filtering unit of the plurality of filtering units.
