Overview

The uDMA (Micro Direct Memory Access) controller serves as a hardware approach for direct data transfers between peripherals/memory and memory without CPU intervention, targeting to off-load CPU from transferring big data chunks where required.

Key features

  • Support up to 8 mem2mem channels with software configurable priority
  • Support up to 32 peripheral channels for pa-mem transfers
  • Support up to 16 (peripheral closely coupled) PER-type of memory-peripheral transfers
  • Support memory access with 1-16 beat(s) incrementing burst type
  • Support configurable data width 8, 16, 32, 64 bits for memory access(depending on data bus width)
  • Support fixed or increasing address generation algorithm
  • Support m2m continuous or repeat configurable-N times transfer mode
  • Support independent source and destination base address setting, byte, half-word or word aligned
  • Support arbitrary transfer block size within (1M-1) bytes
  • Support interrupt generation, masking and clearing

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.
