Description
DMA Controller with AHB interface is full featured, easy-to-use, synthesizable design that can be used with AHB based systems as a controller to transfer data directly from system memory to IP core or from IP core to system memory. Through its compatibility, it provides a simple interface to any IP core with the appropriate logic in between.
Features
-
Supports 1-16 channel DMA Transmit and DMA Receive Engine
-
Compliant with ARM AMBA 2 AHB, AMBA 3 AHB-Lite and AMBA 5 AHB Specification
-
Supports access for Ring and Chained Descriptor Structures
-
Configurable Transmit and Receive Engine based on Host Memory Data Width
-
Configurable support by DMA Transmit and Receive Engine for both of the endianness of the host memory (Little / Big Endian)
-
Supports hardware DMA Control registers that can be written and read by CPU
-
Round Robin algorithm for arbitration between DMA Transmit and Receive Engine to access SOC Master Bus
-
SOC Master bus can be AXI/ AHB/ APB/ OCP/ Tilelink/ Wishbone
-
Supports AHB Slave bus
-
Uses SOC Slave Interface to get Receive and Transmit descriptors and transfer the data to/from the system memory from/to FIFO inside the DMA controller
-
User logic to map data fetched from Host to IP core or from IP core to host
-
Supports Sideband DMA request and Grant based triggering of transfers as on option for peripherals
-
Supports Scatter Gathers list
-
Supports 8/16/32 bit wide data transfers
-
Supports QoS per channel if SOC master interface supports Qos.
-
Supports programmable burst capability per SOC master
-
DMA supports full duplex operation, processing read and write transfers at the same time
-
Supports Link list-based processor for autonomous operation
-
Interface widths can be controller for each SOC master interface
-
Supports configurable DMA Transmit and DMA Receive FIFO based on Host Memory Data width
-
Generate full 32-bit addresses on the SOC master interface.
