Abstract
This article introduces a kind of high speed USB transport system based on the structure of "USB2.0 Slave interface chip + FPGA".The system uses CY7C68013A as USB protocol bridge and FPGA as its control center,and designs optimized finite-state machine to realize synchronous slave FIFO protocol.The USB data high speed transport channel is constructed and the system acquires good performance in real-time processing,transmission reliability and efficiency.At the same time an optimized software loading method is designed to ensure that the system software can be update on line without any manual operation.The test results show that the system can run stably at the average data transfer rate of up to 40 MB/s and the system software can be update automatically in 1.2 seconds.关键词
