基于FPGA的SPI接口AD、DA的通用控制接口
摘要：
本实用新型属于接口装置，具体涉及一种基于FPGA的SPI接口AD、DA的通用控制接口。一种基于FPGA的SPI接口AD、DA的通用控制接口，包括作为输入输出控制的FPGA，和与该FPGA连接并受FPGA控制的AD接口，以及与该FPGA连接并受FPGA控制的DA接口。本实用新型的效果是：利用高速运算的FPGA调用AD、DA接口，实现数据的高速转换和传输，可以最大限度的发挥SPI接口的效率。
摘要（英）：

The utility model belongs to the field of interface devices and particularly relates to an FPGA (Field Programmable Gate Array)-based universal control interface for AD and DA SPIs (Serial Peripheral Interface). The interface provided by the utility model comprises the FPGA for input/output control, as well as an AD interface and a DA interface which are connected with and controlled by the FPGA. The interface provided by the utility model has the benefits that the AD and DA interfaces are invoked through the FPGA in high-speed operation, thereby realizing high-speed conversion and transmission, and playing the efficiency of the SPI to the utmost.
