| Abstract: | A design of RapidIO switch and Flash storage module is proposed aiming at the interconnect bus and data storage problem met in an array signal processing system.The hardware and software design of the module are real-ized.Firstly,the serial RapidIO bus and VPX standard are introduced.The module is designed according to VPX standard.Tsi578 switch is used in RapidIO network to realize the multi-DSP parallel processing system.RapidIO data transfer operation and RapidIO boot mode of the TMS320C6455 DSP are both studied.The software design flow is presented then.NAND Flash is used to realize data storage capability.Finally,the module performance is listed and the data trans-fer speed is tested in the actual signal processing system.The data transfer speed is up to 600MB/s.Experiments show that this design is advanced,realizable and stable,which can be used as a reference design of interconnect bus and data storage. |
