DMA Controller

DTI_DMA control the DMA transfers data between different points in the memory space without intervention of the CPU.

Overview

DTI_DMA control the DMA transfers data between different points in the memory space without intervention of the CPU. The DMA is generally used to replace two CPU functions: memory copy and transfer data between memory and peripheral (peripheral devices such as SPI, UART, GPIO, I2C, I2S, WDT, etc.)

Key features

  • Support 1 to 16 channels (Parameter Configuration)
  • Support maximum 8 peripherals can connect to 1 DMA channel (Parameter Configuration)
  • Channel Arbitration
  • Multiple transfer direction: memory to memory, memory to peripheral, peripheral to memory
  • Single APB Programming Interface (Programming Registers)
  • 2 AXI4 Master Ports (Parameter Configuration)
  • Asynchronus AXI4/APB Interfaces
  • AXI4 Data Width: 32, 64, 128, 256 or 512 bits (Parameter Configuration)
  • AXI4 Address Width: Up to 32 bits (Parameter Configuration)
  • Support source address, destination address, data tran unaligned with AXI4 data size
  • Single FIFO data per channel
  • Automatic packing/unpacking of data to fit FIFO width
  • Support timeout monitoring
  • Data swapping endian mode
  • Interrupt for DMA transfer and channel status
  • Support Scatter-Gather mode
  • Support Circular mode
  • Support Double Buffer mode
  • Support 1D-2D transfer mode

DMA IP Integration

There are many IP’s today . These IP’s can be simple IP’s like Timer to complex IP’s like Accelerators. In Most of the cases IP’s are Integrated in standard way. There are cases where you have the option of Integrating it differently. This goes un-noticed or unable to be implemented due to time constraints. One such IP that would be discussed in this paper is DMA . This paper tries to explain idea of Integrating Direct Memory access(DMA) and Interrupt Control Unit(ICU) differently but final implementation requires some changes in IP. There is a possibility that alternate design explained below may be already implemented.

Moving to AMBA® 5? Your AMBA® 4 IP Can Still Come With You

As SoC architectures adopt AMBA® 5 fabrics and components, many proven IP blocks still rely on AMBA® 4 or earlier interfaces. That creates a common integration problem: how do designers connect newer AMBA® 5 system components to existing IP without redesigning the IP or replacing verified blocks?
