摘要
分析了现有数字信号校准装置存在的问题,提出了一种基于可重构技术的多功能数字信号校准装置的设计方法。该校准装置集频率测量、频率输出等功能于一身,且所处理信号的精度高、范围宽;同时还可根据实际需要,在线地配置硬件资源,从而提高了系统的通用性和灵活性。此外,由于PC104总线、FPGA等嵌入式技术的使用,使得整个装置具有体积小、功耗低、可靠性高、易于携带等特点。
The existing problems of digital signal calibration device are analyzed and a novel one based on reconfiguration technique is presented. The device is of multifunction including frequency-measurement, frequency-output etc, it can handle signals which are of high-precision and wide-range. It also can reconfigure the system＇ s resources depending on the actual need, which improves the device＇ s versatility and flexibility. In addition, the usage of embedded technique, such as the PC104-bus, FPGA etc, makes the device have the features of little-volume, low-cost, high-reliability and easy-portability.
