基于单片机的FPGA在线配置

Configuration Online of FPGA Based on MCU

采用AT89C2051单片机配合E2PROM串行存储器AT24C256,实现对ALTERA公司FLEX10K系列FPGA芯片的被动串行配置。经实验表明,采用单片机对FPGA进行串行配置,读取存储文件不但速度快而且准确,具有配置时间短、准确率高、易于实现等优点。

This design presents an implementation of FPGA passive series configuration to FLEX10K devices of Altera based on AT89C2051 microprocessor and EZPROM memory AT24C256. The experiment demonstrates that MCU has benefits of a high speed and accuracy in reading files stored. Meanwhile, MCU, which processes serial configuration to FPGA, also has advantages of a short time configuration, high accuracy and easy inplementation.
