Abstract
Direct Memory Access (DMA) is used in connection with passing commands between a host device and a target device coupled via a push buffer. Commands passed to a push buffer by a host device may be accumulated by the host device prior to forwarding the commands to the push buffer, such that DMA may be used to collectively pass a block of commands to the push buffer. In addition, a host device may utilize DMA to pass command parameters for commands to a command buffer that is accessible by the target device but is separate from the push buffer, with the commands that are passed to the push buffer including pointers to the associated command parameters in the command buffer.
