这是一个关于FPGA得技术资料。里面详细的说明了用法

单端反激式开关电源具有结构简单、输入输出电气隔离、电压升／降范围宽、易于多路输出、可靠性高、造价低等优点，广泛应用于小功率场合。然而，由于漏感影响，反激变换器功率开关管关断时将引起电压尖峰，必须用钳位电路加以抑制。由于RCD钳位电路比有源钳位电路更简洁且易实现，因而在小功率变换场合RCD钳位更有实用价值。 -Single-ended flyback switching power supply with a simple structure, input and output electrical isolation, voltage up/down range, easy to multi-output, high reliability and low cost, widely used in low-power occasions. However, due to leakage effects flyback converter power switch off when the voltage spike caused by the need to be inhibited by clamping circuit. RCD clamp circuit as a result of active-clamp circuit than the more concise and easy to realize, and in low-power transform RCD clamp occasions more practical value.

提出了基于嵌入式技术CCD 采集系统的新方法,并以ARM微处理器和FPGA 芯片为核心设计了嵌入式CCD 采集系统,解决了传统采集方法中系统过于庞大和复杂的问题,具有结构简单、小型化和智能化的特点。试验结果表明,该系统实现了CCD 输出图像的高速采集和实时显示,数据采集速率达到5 MHz。-Embedded technology based on CCD acquisition system A new method, and ARM microprocessors and FPGA chip is designed as the core embedded CCD acquisition system to address the traditional acquisition methods in the system too large and complex problems, is simple in structure, small and intelligent features. Experimental results show that the system realizes high-speed CCD output image acquisition and real-time display, data acquisition rate up to 5 MHz.
