基于DSP/BIOS的多机通信系统的设计与实现

Design and Implementation of a Multi-machine Communication System Based on DSP/BIOS

数字信号处理器(Digital Signal Processor,DSP)在电子设计中应用广泛,DSP/基本输入输出系统(Basic Input Output System,BIOS)则是TI公司推出的一个应用于DSP平台的实时嵌入式操作系统,为设计多任务程序带来极大便利。以TMS320C5509A芯片为例,结合具体工程实践,设计了基于DSP/BIOS的多机集成电路总线(Inter-Integrated Circuit,I2C)通信系统。分析中断处理流程和数据发送流程,并指出设计过程中应该注意的相关问题,给出了系统稳定性和中央处理器(Central Processing Unit,CPU)利用率的测试结果,对相关工程实施具备很好的指导作用。

Digital Signal Processor(DSP)is widely used in electronic design,and DSP/Basic Input Output System(BIOS)is a realtime embedded operating system applied to DSP platform,which brings great convenience for designing multi-task programs.Taking TMS320C5509A chip as an example,combined with specific engineering practice,a multi-machine Inter-Integrated Circuit('C)communication system based on DSP/BIOS is designed.This paper analyzes the interrupt processing flow and data sending flow,points out the related problems that should be paid attention to in the design process,and gives the test results of system stability and utilization rate of Central Processing Unit(CPU),which has a good guiding role for the implementation of related projects.
