For　the　huge　amount　of　image　data,　high　transfer　rate,　high　real-time　requirements　of　the　imaging　system,　this　paper　proposes　a　high-speed　image　data　acquisition　and　storage　system　based　on　TMS320C6748　DSP,　with　the　use　of　uPP　interfaces　to　capture　images　from　the　FPGA　in　real　time,　using　GPIO　and　UART　to　implement　synchronous　work　between　FPGA　and　DSP,　using　external　DDR2　memory　to　design　Ping-Pong　buffering　mechanism　to　ensure　real-time　hard　disk　storage　of　huge　image　data.　Experimental　results　show　that　the　designed　system　can　achieve　image　data　acquisition　and　storage　both　stably　and　rightly　in　the　high-speed　data　transmission.
