Research And Realization On Platform Of CompactPCI-to-VME Bridge

For the past 20 years, VME bus was broadly used in the embedded computers of theindustry, commerce and military systems, particularly in the traffic controlling systems,weapon controlling system, telecommunication systems, data capturing and video imagingsystems and robots. Due to the ever increasing bandwidth requirements, the higherperformance CompactPCI (Compact Peripheral Component Interconnect) bus has beenreceived significant interest for use in such systems. Migration to the PCI bus from the VMEbus has a number of complications associated it. The hybrid space system architectureincorporating both the VME and CompactPCI buses has been developed to solve the problem.This thesis presents the design and the implement integration scheme for CompactPCIand VME bus. For the moment we have tested the performance of the bridge backplane usingthe PCI-to-VME bridge—Universe II. The result shows that the developed platform ispractical. Meanwhile, we guarantee that there is no need to change the boards of CompactPCIand VME. This can save much time as well as money for the integration of both buses.First, this thesis introduced the CompactPCI and VME bus. Second, how to bridge theCompactPCI and VME buses with Universe II was introduced in detail, including thecharacteristics, applications and working principle of the Universe II and the possible schemeof the platform. Third, this thesis discussed how to port the bridge driver and deal with theproblems during debugging. The experiments show that the developed backplane with thePCI-to-VME Bridge is practical. Finally this thesis discussed the test of bus performance andalso introduced the test process in the digital cinema.
