FPGA Architecture for Image Processing Based on FLASH-SRAM Memory

The embedded technology and its applications are growing in the industry and research areas. An important application is the image processing, but these process requires a lot of resources and computing time. This paper presents a digital system for image processing, using FPGA technology. The image is send from PC to the digital system through RS232 interface, and the image is recorded on a FLASH memory. Once the image is stored, the image is translated to RAM memory to execute the process and the image processed can be displayed in a VGA interface. The proposed architecture is standard VHDL to design the hardware description. The architecture developed can be adjusted to be used on any FPGA platform with minimum changes. The architecture is tested with an image of 640×480 pixels and the results are compared with the Mat lab software.
