| Abstract: | According to the problem between real-time image processing and mass data, dual-port random ac-cess memory （RAM） used in image processing system is presented. The functions and characteristics of dual-port RAM are introduced. Taking IDT70V09 chip as an example, system structure, hardware interface, system software design of dual-port RAM used in image processing system and the detailed design of dual-port RAM operation soft-ware of field-programmable gate array （FPGA） and data signal processor （DSP） are given. And the port contention problem of dual-port RAM and the solutions are discussed in detail. The suggestions about printed circuit board de-sign and circuit debugging of the system are proposed. Finally, function test of the image processing system is per-formed to prove the stability and feasibility of the system adopting dual-port RAM design. |
