Abstract

A direct memory access (DMA) circuit is provided. The DMA circuit may include a plurality of groups of direct memory access channels, wherein each of the groups includes at least one DMA channel and a resource usage counter configured to count an execution time in which one of the DMA channels of the group is executed, and an arbiter configured to evaluate a value of the resource usage counter of a group upon a request for execution time by one of the DMA channels of the group, and, taking into account a result of the evaluation, to assign, delay assignment, or deny execution time for using the direct memory access to one of the groups.
