基于FPGA和ARM的高速数据共享方法设计

随着仪器朝小型化,便携式的发展,单位面积内实现的功能势必会越来越多,越来越复杂.而单一处理器显然无法满足这种发展要求.因此,多处理器协同工作来完成系统任务已经成为一种趋势.处理器的架构不同,完成不同功能时性能就有所差别.根据系统的设计需求,选择合适的处理器是非常关键的.而不同处理器协同工作时,就会遇到数据共享的问题.当数据量共享要求较低时,通过普通的通信协议就可以完成.但是当需要共享高速和高可靠性的数据量时,普通的传输方式已经无法满足要求.根据此需求,提出了一种高效的数据共享方法.经检测,系统性能工作良好,数据传输稳定.

Design of Method of High Speed Data Sharing Based on FPGA and ARM

It becomes a tendency that multiprocessor has a cooperative work.As the differences of processor architecture,the performance is different when processor processes＇ the same function.It is important that selecting a suitable processor according to the requirements of the functions.However,one problem sharing data between two processors must be solved. Generally,if few data are transmitted,could use ordinary communication protocols,such as IIC or SPI,to finish this task.But if the data are large,ordinary methods can＇t obviously meet requirements.This paper presents a method to solve this problem effectively.System works well and data transmit steadily after test.
