基于ARM和FPGA的红外系统数据交换驱动设计

Driver Design of Infrared System Data Exchange Based on ARM and FPGA

首先对基于ARM和FPGA的红外监控系统的采集、处理、传输、显示模块进行简要介绍,重点对ARM模块和FPGA模块之间接口进行设计,然后在Linux操作系统下对ARM和FPGA之间数据交换驱动程序进行分析设计。对驱动设计的主要流程和具体实现过程进行详细介绍,提出等待队列和DMA传输结合的方式进行数据传输,经过实际性能测试,该方案极大提高系统效率。

The acquisition, processing, transmission and display module of the infrared monitoring system which is based on ARM and FPGA are briefly introduced. The design of the interface between ARM and FPGA module is focused on. Then, based on the Linux operating system, the driver of data ex- change between the ARM and FPGA is analyzed and designed. The main process and the specific implementation process of the driver design in detail are introduced, and the method to combine waiting queue and DMA transmission in order to transmit data is put forward. Through the actual performance test, the method can greatly improve system efficiency.
