In order to meet the request of high-speed data exchange in embedded systems, this paper details the high-speed SRIO (Serial RapidIO) interface protocol and the process of SRIO access timing between the local endpoint devices and the remote endpoint devices. And also we implement the design of the new high-performance RapidIO interconnection between DSP and FPGA. Through the performance testing of SRIO data transmission system, experimental results show that the design can stably transfer data at high speed between processors.

Based on the target detection of alignment template, the paper designs a lane alignment template by using correlation matching method, and combines with genetic algorithm for template stochastic matching and optimization to realize the lane detection. In order to solve the real-time problem of lane detection algorithm based on genetic algorithm, this paper uses the high performance multi-core DSP chip TMS320C6474 as the core, combines with high-speed data transmission technology of Rapid10, realizes the hardware parallel processing of the lane detection algorithm. By Rapid10 bus, the data transmission speed between the DSP and the DSP can reach 3.125Gbps, it basically realizes transmission without delay, and thereby solves the high speed transmission of the large data quantity between processor. The experimental results show that, no matter the calculated lane line, or the running time is better than the single DSP and PC at the parallel C6474 platform. In addition, the road detection is accurate and reliable, and it has good robustness.
