DSP芯片是目前流行的数字信号处理芯片,它不仅有极强的运算能力,同时具有丰富的硬件资源。本文将介绍浮点DSP芯片TMS320C3X的串行通信的特点,由于该浮点DSP芯片是为TMS320系列DSP芯片和某些特殊芯片的通信而设计的,与常用的串行通信协议不兼容,本文将介绍一种设计方案,使其实现与PC机等的常用串行协议通信。 DSP chip is the popular digital signal processing chip, it not only has strong computing power, but also has a wealth of hardware resources. This article will introduce the characteristics of floating-point DSP chip TMS320C3X serial communication, as the floating-point DSP chip is designed for the TMS320 series DSP chip and some special chip communication, and the common serial communication protocol is not compatible, this article will Introduce a kind of design scheme, make it realize with the PC and other commonly used serial protocol communication.
