Dedicated direct memory access router system and method

Abstract

A direct memory access (DMA) router including interrupt inputs, action groups and a DMA router engine. Each interrupt input is configured to receive a corresponding interrupt signal. Each action group is associated with a corresponding interrupt input and is configured with at least one DMA action, in which each DMA action is configured to select a DMA controller and a corresponding channel. The DMA router is configured to initiate a transfer using a selected channel of a selected DMA controller for at least one DMA action listed in an action group associated with a corresponding interrupt input triggered by assertion of a corresponding interrupt signal. The DMA actions may indicate dependencies, such that the DMA router may initiate a second DMA action only after completion of a first DMA action within the same action group based upon the indicated dependency.

Dependencies are inferred from the claim text.
