Electron　Multiplying　Charge　Coupled　Device　(EMCCD)　is　a　kind　of　high　sensitive　imaging　device,　widely　used　in　shimmer　detection　field.　The　paper　proposed　a　design　of　image　processing　system　for　CCD201,　an　EMCCD　with　high　frequency　and　high　sensitivity　of　E2V　Corporation.　We　selected　the　Xilinx　product　ZYNQ-7000　series,　based　on　ARM+FPGA　architecture,　as　the　processor.　According　to　the　amount　of　image　data　and　the　complexity　of　image　processing,　the　specific　model　was　determined　as　ZYNQ-7030.　We　designed　a　set　of　memory　system　out　of　chip　and　communication　interface　for　the　processor.　To　improve　power　conversion　efficiency　and　minimize　the　system,　a　4-channel　DCDC　micro-module　LTM4644　was　selected.　LTM4644　has　lower　output　voltage　ripple　than　common　DCDC　part　and　can　meet　the　power　noise　request　of　the　system.
