Method and apparatus for determining priorities in direct memory access device having multiple direct memory access request blocks

A priority determining method and apparatus can reduce a total waiting time of DMA request blocks by granting priority to each of Direct Memory Access (DMA) request blocks transmitting a DMA request signal, based on Data Transfer Amounts (DTAs) of the DMA request blocks and Arrival Times (ATs) of th...

description A priority determining method and apparatus can reduce a total waiting time of DMA request blocks by granting priority to each of Direct Memory Access (DMA) request blocks transmitting a DMA request signal, based on Data Transfer Amounts (DTAs) of the DMA request blocks and Arrival Times (ATs) of the DMA request signals, counting the number of priority changes of each of DMA request blocks whose priority is changed in the priority granting process, and if a DMA request signal is received from a new DMA request block, determining priorities of the DMA request blocks based on the counted the number of priority changes.
