Performance evaluation PL330 DMA controller for bulk data transfer in Zynq SoC

This paper provides performance evaluation of PL330 DMA in Zynq SoC based device. Direct Memory Access is the feature that allows computer hardware to access system memory for data movement in bulk without CPU intervention. The I/O devices operate at a slower speed than CPU, but using DMA the CPU can be available for performing other computing tasks while data is transferred, as CPU has to only initiate the read/write of data. The direction of transfer can be from device-to-memory, memory-to-device, memory-to-memory and device-to-device. This paper describes the hardware setup and sequence of operations for transfer of bulk volume data at high speed using PL330 DMA controller in Zynq SoC based system.
