Design Of Multiprocessor Parallel System Based On Vxibus

With the development of ratio technology, the ratio-communication operation hasbeen largely promoted.For making use of frequency resources effectively and makingair channel free, we need ratio monitoring necessarily.In the last few years, with thedevelopment of software ratio technology, the level of the monitor equipments alsoobtained the big advance. In this paper, the broadband monitoring receiver adopts VXIbus technology andsome other technologies such as the latest software ratio technologies, DSPtechnologies. The research of the monitoring receiver can satisfy the actual need ofratio monitors in our country. With the fast development of DSP technologies,the DSPs are widely applied inmany fields,such as communications,aviations and spaceflight, medical treatmentinstrument,industry control and so on.The DSP has many merits,included flexiblesystem forms,programmable,high speed calculation,strong capability in dataprocessing and communication,and extensive applicability. In this paper, the main research is the software and the hardware design of themultiprocessor module.The broadband monitoring receiver requires a kind of chipwith high performance because of complicated intermediate frequency signalprocessing.The author adopts a kind of high proformance digital signal processorcalled ADSP-TS101.ADSP-TS101 provides high working frequency, strong floatoperation capability, high speed data processing and internal memory with largecapacity. It adapts to be applied to large complete digital data processing inradar,sonar and software ratio system.The author put forward a kind of twoTigerSharcs system.The first ADSP-TS101 read data from A/D module directly.Thetwo TigerSharcs transmit data from each other through LinkPorts. In thismutiprocessor system, the author adopts a EPROM to load the two processors.Thethesis discusses the PCB and software arithmetic simply and put forward someeffective means.
