基于FPGA的PEX8112配置模块的设计及实现

Realization and Design of the PEX8112 Configuration Module Based on FPGA

介绍了一种基于FPGA的可用于PEX8112芯片的寄存器配置的设计方法,详细说明了SPI接口协议及用FPGA来实现寄存器配置模块的设计过程,在Quartus Ⅱ中对设计模块进行了仿真验证,最后通过硬件测试证明了设计方法的正确性和可靠性。该方法对用FPAG配置其它芯片具有普遍适用性。

The design method for the PEX8112 register module based on FPGA is presented. The configuration module SPI bus design process is introduced in detail. The result is simulated with Quartus Ⅱ Hardware tests show that this method is correct and reliable. The method applies generally to chips configuration.
