磁盘控制器

Secondly, the thesis analyzes the design principle of hardware system, and descries the architecture of the solution. It analyzes how to implement AD converter, IDT72V3690 circuit, FPGA chip EP1C2214 design, including RAIDO disk control and application of embedded microprocessor LPC2214.Thirdly, the thesis descripts the design and realization of embedded software of LPC2214. First of all, it brings out the thinking of software layer, and designs the software architecture.

其次，叙述了基于USB总线硬件系统的体系结构及设计原理；详细介绍了如何实现AD转换电路抗干扰以及如何采用嵌入式处理器LPC2214、高速缓存IDT72V3690电路、FPGA芯片EP1C2214等电路设计实现简易RAID0存储阵列；重点叙述了FPGA设计ATA控制器和RAIDO逻辑的过程，介绍了FPGA内部逻辑是如何工作，将数据有序高效地并行存储到磁盘中去的。

This raid controller in general is equipped with a specific processor, memory, and is able to manage all RAID system version ( thanks to the build in firmware ).

这次空袭控制器一般配备一个具体的处理器，内存，并能够管理所有的磁盘阵列系统版本。

So plug in a key test, the system prompts to find new hardware and automatically install the driver to start, after a few steps, a removable disk drive letter appears in the Explorer, This shows that all the normal USB controller.

于是插上一个闪盘进行测试，系统提示找到新硬件，并开始自动安装驱动，经过几个步骤之后，一个可移动磁盘的盘符出现在资源管理器中，这说明USB控制器一切正常。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
