The Design And Realization Of High Speed Serial Interface Of SRIO Based On TMS320C6455

The research and manufacture of General Digital Signal Process module based on Digital Signal Processor satisfied the requirement of Signal Processing System for real-time and general use. However, with the development of modern science and technology, on the one hand, in order to realize the computation and digital signal processing algorithm of real-time demand is higher and higher, higher processing performance, faster computing speed of digital signal processor. On the other hand in view of the current of the complexity of the application, to meet the requirements of application and the media, the signal processing system needs to integrate many interfaces. These challenges mostly deal with two subjects. The first one is process capability, which means processing resources available in the equipments, the boards and the systems; the other one is connectivity, in essence is to realize the fast data transfer between different equipment, the board and the system.The main research content of this thesis and engineering design implementation work specific as follows:(1) Through in-depth analysis of high speed serial interface SRIO transmission technology development trends and direction of development at home and abroad,research SRIO transmission specification and basic characteristics of clear SRIO interface within the currently used for plate or plate communication between the mainstream of the high speed signal interface in the dominant position;The study of SRIO communication protocol;(2) Based on SRIO communication protocol, transaction packet format, SRIO transmission basic flow and SRIO communication key technology of system research, for the design and implementation of a high-speed serial interface SRIO TMS320C6455 provides the theoretical basis;(3) SRIO communication system is introduced in this paper, the complete system from the processor TMS320C6455 SRIO high-speed serial interface hardware design;(4) Through to the TMS320C6455 SRIO register generalization, complete the research and design of DSP SRIO interface drivers, at the same time to complete the BSP with API interface function between the upper application software;(5) Introduce TMS320C6455 software loading way and load process, SRIO guided mode to realize the main processor Power dynamic loading of the PC of DSP software, after loading of the software, DSP will be able to run normally;(6) Design verification complete TMS320C6455 SRIO interface communication, DSP communication with the main processor(P2020) and logical unit(FPGA) can be achieved through SRIO interface, so as to illustrate the correctness of the TMS320C6455 SRIO interface design.
