DS_DMA

h1. Struct

The basis of the controller is a component of [[pcie_core64_m1]]

It combines IP Core Xilinx, core logic for generation and reception of packets, access to the registers and the DMA controller.

Block diagram:

The component has two buses:

* Bus [[BAR0 Bus]] - to access the registers BAR0

* Bus [[PLD Bus]] - for single and block calls to the BAR1

DMA channel only works with the bus PLD Bus.

In the space BAR0 implemented control registers. They are grouped into blocks of control. To control the DMA channels control blocks allocated 4.5;

Access to the control block 0-3 is performed through the bus [[BAR0 Bus]].

Component [[pcie_core64_m2]] is an example of a controller in the system. It adds a control block BLOCK_MAIN and local bus [[LC Bus]]

Component [[pcie_core64_wishbone]] as an example of a controller in the system. It adds a control block BLOCK_MAIN and local bus [[WISHBONE]]
