摘要: 主机扩展总线接口E-Bus是为自主研发的数字信号处理器(DSP)芯片YHFT-DSP开发的外围并行接口,能有效支持DSP与各种同步、异步接口的商业标准主机进行数据交换。为了有效地研制、测试和应用E-Bus,开发了一套基于E-Bus的DSP仿真测试平台。该平台采用软硬件协同仿真和现场可编程门阵列(FPGA)技术实现了E-Bus和USB2.0接口的协议变换。实验结果表明,测试平台具有良好的操控界面,实现了E-Bus主/从两种模式下外部主机与YHFT-DSP之间的数据交换。

Abstract: The E-Bus is a peripheral parallel interface of a self-developed Digital Signal Processor (DSP) chip named YHFT-DSP. It could support various synchronous or asynchronous commerce standards of host-device interface protocols in order to exchange data effectively between them. In order to design, test and apply the E-Bus interface effectively, a set of simulation platform based on E-Bus was implemented. It used hardware/software cooperation and Field Programmable Gate Array (FPGA) technology to carry out the protocols transformation between E-Bus and USB2.0. The results of test show that the platform has a nice operable interface and implements the data exchange functions between host-device and YHFT-DSP under the master or slave modes of E-Bus.

Key words: Digital Signal Processor (DSP), Host Port Interface (HPI), protocols convertor, test
