6.5.7.1 Direct Memory Access (DMA)

The DMA controller is known as micro-DMA (µDMA). The µDMA controller provides a way to offload data transfer tasks from the Cortex-M4F processor, allowing for more efficient use of the processor and the available bus bandwidth. The µDMA controller can perform transfers between memory and peripherals. It has dedicated channels for each supported on-chip module and can be programmed to automatically perform transfers between peripherals and memory as the peripheral is ready to transfer more data. The µDMA controller provides the following features:

  • Arm PrimeCell 32-channel configurable µDMA controller
  • Support for memory-to-memory, memory-to-peripheral, and peripheral-to-memory in multiple transfer modes
    • Basic for simple transfer scenarios
    • Ping-pong for continuous data flow
    • Scatter-gather for a programmable list of up to 256 arbitrary transfers initiated from one request
  • Highly flexible and configurable channel operation
    • Independently configured and operated channels
    • Dedicated channels for supported on-chip modules
    • Flexible channel assignments
    • One channel each for receive and transmit path for bidirectional modules
    • Dedicated channel for software-initiated transfers
    • Per-channel configurable priority scheme
    • Optional software-initiated requests for any channel
  • Two levels of priority
  • Design optimizations for improved bus access performance between µDMA controller and the processor core
    • µDMA controller access is subordinate to core access
    • RAM striping
    • Peripheral bus segmentation
  • Data sizes of 8, 16, and 32 bits
  • Transfer size is programmable in binary steps from 1 to 1024
  • Source and destination address increment size of byte, halfword, word, or no increment
  • Maskable peripheral requests
  • Interrupt on transfer completion, with a separate interrupt per channel

Each DMA channel has up to nine possible assignments that are selected using the DMA Channel Map Select n (DMACHMAPn) registers with 4-bit assignment fields for each µDMA channel.

Table 6-2 lists the µDMA channel mapping. The Encoding column lists the encoding for the respective DMACHMAPn bit field. Encodings 0x9 to 0xF are reserved. The Type column indicates if a particular peripheral uses a single request (S), burst request (B), or either (SB).

NOTE

Channels or encodings marked as Reserved cannot be used for µDMA transfers. Channels designated in the table as only "Software" are dedicated software channels. When only one software request is required in an application, dedicated software channels can be used. If multiple software requests in code are required, then peripheral channel software requests should be used for proper µDMA completion acknowledgement.
