TMS320C54X系列DSP与计算机并口通信设计

The Design of Communication between TMS320C54X DSP and PC Parallel Port

简要介绍了TI公司的TMS320C54X系列DSP的HPI接口以及计算机并口的EPP模式,并提出了利用EPP模式自动产生握手信号与软件产生握手信号相结合的方式实现HPI与并口通信的方案。该方案以简单的电路和软件设计实现了DSP与主机的数据块的传输,并具有较高的传输速度。

The article simply introduces the HPI of TI's TMS320C54X DSP and EPP model of PC Parallel Port Interface, and puts forward a new application which combines automatic handshake signal generation and softerware signal generation to achieve communication between parallel Port and HPI. The application achieves communication of date block between DSP and PC with simple circuit and sofware,and also has a high speed.
