Tera-scale performance image stream processor with SoC architecture for multimedia content analysis
A 1.0 TOPS image stream processor, which deals with image processing tasks for multimedia content analysis, is implemented with 2.2mm2 area in 90nm CMOS technology. Two sub processors, linear processor and order processor, are integrated to achieve tera-scale performance. In the proposed SoC architecture, the data are transferred between processors and the high bandwidth dual memory through the local media bus, which reduces the power consumption in the AHB data access. Based on the memory architecture, the maximum input data rate of the proposed image stream processor reaches 62.5 Gpixel/s, which meets the requirements for real-time HDTV image processing.
