DMA implementations for FPGA-based data acquisition systems

摘要

The paper describes three implementations of DMA engines created for different data acquisition (DAQ) systems. The designs are based on vendor (Xilinx) provided IP cores. The emphasis is put on typical problems related to the implementation of high-performance data acquisition systems. The selection or building of proper DMA cores is shown, and typical problems associated with the realization of the device driver are described. Sources of the described systems are publically available.
