一种FPGA配置新方法在阻抗成像系统中的应用

Application of a New Method to Configuring FPGA in EIT System

针对在单片机或嵌入式系统中通过串口或IO口配置FPGA速度较慢的问题,提出了一种利用SPI接口实现FPGA配置的新方法。该方法提高了FPGA的配置速度,并成功地应用到了阻抗成像系统中。详细介绍了利用LPC2210的SPI接口配置FPGA的方法。

To tackle the problem of the slow speed of using UART or IO port to configuring the FPGA in microcontroller or embedded system, a new method of the configuration of FPGA by using serial peripheral interface is put forward. This method improves the speed of the configuration of FPGA, and it has been applied to EIT system successfully. The method of using serial peripheral interface of the LPC2210 to configuring the FPGA is elaborated.
