基于USB2.0的任意波形发生器设计

Design of Random Waveform Generator Based on USB2.0

基于USB2.0芯片CY7C68013,对以D/A为核心的任意波形发生器进行研究。实现了对任意波形数据的存储与回放。详细介绍了系统的总体结构、波形发生器硬件电路及其与CY7C68013的接口设计,并对基于GPIF主控方式的固件程序开发作了重点论述。

This paper researches the D/A based random waveform generator based on CY7C68013, and realizes the storage and replay of random waveform data. In this paper, correlative main content are introduced in detail, including general architecture of system, design of hardware circuit of random waveform generator and its' interface to CY7C68013. Furthermore, the development of corresponding firmware based on GPIF is described emphatically.
