In this paper we proposed a new energy saving system whose multiple switches are operated independently according to the regional movement detection in video stream. This system consists of embedded vision system and LED switching circuit, communicating each other through GPIO. Embedded vision system is implemented by 32 bit RISC processor, OpenRISC and peripherals - SDRAM, SSRAM, DMA, TFT-LCD, GPIO and CIS, etc. - connected on Wishbone on-chip bus. One bus structure is too busy to provide enough high speed transferring of image data from camera both to TFT-LCD and to the processor that is executing motion detecting program. So segmented bus structure is introduced to achieve higher performance. It is verified by simulation that the performance of segmented bus structure is more than two times better than one bus structure. The FPGA implementation confirms higher data transferring speed, suitable for a real-time video application. |
