Study of Image Real-time Compression Technique

An image real-time compression system based on multiple-mode adaptive compression algorithm has been developed .The system comprises several processors working in parallel mode ,and each processor adopts pipeline working pattern ,so the capacity and the data processing speed of the system are adjustable .The ASIC of the processor has been designed and manufactured by using VHDL and FPGA .The peak processing speed of a single processor can reach 100 Mbit/s .The compression rate can be adjusted dynamically and the PSNR of restored image varies from 35dB to 45dB.The system is characterized with low power consumption , small size, low weight.
