摘要
在目前大多开发商使用单芯片方法解决USB2.0模块设计问题的情况下,从多芯片设计方法入手,提出了一种新系统设计方案,并且提出了对应的Firmware(固件)设计的解决流程。首先简要介绍了USB2.0标准,并以NETCHIP公司的NET2270 USB控制器芯片设计为例,提出了以NET2270为核心,配合其他功能芯片,设计符合USB2.0规范的外设端通信模块的方法和新的系统结构,并在实际系统测试中实现了高速数据传输。
In this article, the new method of the system design about the USB2.0 communications module with multi-chips solution is proposed and the solution of correspondent firmware design is also introduced. At first, the standards and technology characteristic of USB2.0 are introduced in this paper, then it is put forward that a new system module structure and the firmware design idea as well as programming flow of according with USB2.0 protocol, with example of NET2270 controller by author. At last, the test results of a high-speed data transmission are introduced.
