嵌入式Linux下FPGA与ARM处理器DMA数据采集程序设计

On DMA Data Collection Program Design Between FPGA and ARM Processor in Embedded Linux

在嵌入式系统的高速数据采集过程中,往往需要使用到FPGA与ARM之间的DMA技术,这其中,FPGA在嵌入式Linux下的DMA驱动程序是难点.介绍了在实际工作的过程中,如何实现FPGA的DMA驱动,完成从FPGA中采集红外热图数据的实时传输.

In high speed data acquisition process in embedded systems, it is often needed to technology between the FPGA and ARM, in which DMA driver FPGA embedded Linux point. In this paper, a FPGA DMA drivers has been realized to complete a collection of real sion of the infrared image data from FPGA.
