Application Research on Dual-port RAM in Image Processing System
According to the problem between real-time image processing and mass data, dual-port random access 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 software 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 design and circuit debugging of the system are proposed. Finally, function test of the image processing system is performed to prove the stability and feasibility of the system adopting dual-port RAM design.
