摘要
描述了TMS320VC5402主机接口HPI的工作原理,利用HPI口实现TMS320VC5402与AT89S52通信,给出HPI接口的硬件设计及软件设计,不需要增加额外的硬件设备与软件开销。实现了一种DSP系统与单片机系统通信的硬件连接方案和软件实现方法,给出软件程序流程图。实验证明,该系统具有数据传输速度快,适用于其他含有HPI接口的DSP应用系统,对于一些复杂系统的设计具有一定的参考价值。
Working principle of the HPI of TMS320VC5402 is described, the using of HPI achives communications between TMS320VC5402 and AT89S52, hardware design and software design of the HPI interface is introduced, do not add the expenses of hardware and software. A DSP system and the single chip computer system hardware communications connectivity solutions and software implementation methods are implemented,a software program flowchart is given. Experiments prove that the system has a quick data transmission speed, applicable to other HPI interface containing DSP application system, it has good reference for some complex systems design.
