Design of PXI Express Embedded Controller

Abstract

Based on PXI Express bus protocol and PXI Express hardware specification, PXI Express embedded controller is designed in this paper. MPC8536 is taken as a processor in the overall hardware program. FPGA and PXI Express Switch are taken to design PXI Express interface. Cut and customed VxWorks OS is taken in the software program. U-boot ensure normal operation of the embedded controller. BSP boot the VxWorks OS to complete the normal start up, then check the function of each part. Finally, a test platform of AD data acquisition module is built to verify the design.
