The Research into the Key Problem of Multi-Channel Video Acquisition and Display System Based on FPGA

Article Preview

Abstract:

Aimed at the problem of the embedded multi-channel video acquisition and display system, a new one based on FPGA is put forward. The configuration of the system is given. The principle and key issue is analyzed. Using of the state shift mechanism, t the controlling time sequence signals of TFT-LCD are produced; The synchronization among multi-channel video acquisition is realized by using time-division multiplexing technology; The problem of conflict between reading and writing frame cache is solved through the two SRAM switch; The frames composition technology is applied to accomplish the change from interlaced scanning to progressive scanning. The result of project application shows the virtues of system, such as good effect of acquisition and display, low cost and low power consumption.
