Short Desc. : Configurable Multi-Channel AHB GPDMA Core
Overview :
The General Purpose DMA (GPDMA) block support’s 4 DMA channels on AHB bus, using 2 AHB masters. Each DMA channel enables movement of data from a source AHB address to destination AHB address, for a pro-grammed count. Each channel executes a command stored in a descriptor. Several descriptors can be linked in a linked list before the DMA completes.
Features : - Supports 4 DMA channels.
- Uses 2 AHB masters, and 1 AHB slave.
- AHB 2.0 (32-bit) compliant.
- Supports SINGLE, INCR, INCR4 AHB transfers
- Linked List of descriptors having command and status enables mul-tiple data movements to be done before completion interrupt.
- DMA request inputs for source and destination control DMA access time
- Programmable source and destination inputs for each DMA channel.
- 16 Byte register buffer per channel
- Fully synchronous design without latches.
