一种DSP高可靠性快速数据传输方法的研究
Study on High-Reliability and High-Speed Data Transmission on DSP
摘要
Abstract
Asynchronous data and high error rate always happen in DSP data transmission. To avoid those problems, data transmission method is designed based on DSP,through FPGA/CPLD expansion peripherals,and taken frame synchronization and CRC. Based on a DSP hardware design,a new communication protocol is defined which depends on finite state frame synchronization and calculated by byte CRC. The data stores in the data frame to transport. Through some tests,the method can improve the efficiency,stability,security of the DSP system. It also adapts the occasions which large amount and high-speed data transfer.关键词
