摘要

 

进入21世纪之后,数字化浪潮正在席卷全球,数字信号处理器DSP(Digital Signal Processor)正是这场数字化革命的核心,无论在其应用的广度还是深度方面,都在以前所未有的速度向前发展。数字信号处理是利用计算机或专用处理设备,以数字的形式对信号进行分析、采集、合成、变换、滤波、估算、压缩、识别等加工处理,以便提取有用的信息并进行有效的传输与应用。

本文提供了解决DSP与计算机异步串行通信的软硬件解决方案。采用 TI 公司的通用异步接收发送设备 UART芯片完成数字信号处理器 DSP与 PC 机之间的串行通信,可以避免常规的对DSP 的多通道缓冲串口 MCBSP复杂的软件编程模拟,不仅编程简单,传输能力强,而且实时性好,可靠性高。文中介绍了一种 UART 芯片 TL16C550, 并给出了它与 TMS320VC5402 连接的硬件电路以及软件编程方法。

SERIAL COMMUNICATION BETWEEN DSP AND COMPUTER

 

ABSTRACT

 

After entering the 21st century, the digitalization tide is sweeping the globe, Digital Signal Processor (DSP) is the core of the Digital revolution, no matter in the application of breadth or depth is still at an unprecedented rate of forward development. Digital signal processing is to use computer or special treatment equipment, in digital form on signal is analyzed, collection, synthesis, transform, filtering and estimation, compression, identification processing, in order to extract useful information and effective transmission and applications.

This paper provides UART for a solution to communication between DSP and PC. The serial communication between DSP and personal computer can be realized by using UART CMOS chip of Texas Instruments Inc., which can avoid writing the complicated software routine for the McBSP of DSP, and has the advantages of simple programming high transmission capability, good reliability and real time capability. In this paper, we introduce briefly a kind of UART COMS chip TL16C550 and provide the hardware circuit between TL16C550 and TMS320VC5402 and the way how to program it.

 

Key words: Serial Communication;DSP;TL16C550;TMS320VC5402
