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 are analyzed. Using the status shift mechanism

the protocol of I

2

C is realized and the controlling time sequence signals of TFT-LCD are produced. The synchronization among multi-channel video acquisition is achieved by using time-division multiplexing technology. The problem of conflict between reading and writing frame cache is solved through the two SRAM switch. The frame composition technology is applied to accomplishing 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.
