The design of image acquisition and display system

Abstract

The FPGA with Avalon Bus architecture and Nios soft-core processor developed by Altera Corporation is an advanced embedded solution for control and interface systems. a embedded system with A CCD data acquisition system and a VGA display module is very common in the industry design. With the rapid development of embedded systems, in particular the development of high-speed image processing, displaying the real-time image processing is very important. Based on the principle of VGA display, abandoning VGA display dedicated chip and using SOPC (Programmable System-on-Chip) technology, embed Nios II 32-bit processor soft-core in the FPGA (Field Programmable Gate Arrays) chips, Through programming the image acquisition module, DMA control module, VGA display and control module, VGA image acquisition and display controller is designed. VGA display system based on this method is a small size, low power consumption and high reliability.
