Bases: BasePeripheral

Direct Memory Access controller for efficient data transfer between memory and peripherals.

Parameters:

  • ch_length (int) – The length of each channel in the DMA.

  • length (int) – The length of the DMA.

  • num_channels (int) – The number of channels in the DMA.

  • num_master_ports (int) – The number of master ports in the DMA.

  • num_channels_per_master_port (int) – The number of channels per master port in the DMA.

get_addr_mode()

Get the address mode of the DMA.

get_ch_length()

Get the length of each channel in the DMA.

get_fifo_depth()

Get the depth of the DMA FIFO.

get_hw_fifo_mode()

validate()

Checks if the DMA peripheral is valid (number of channels between 0 and 256, master ports between 0 and number of channels, channels per master port between 0 and number of channels, number of channels per master port is not 0 if number of channels is not 1).
