Embedded Co-Processor Architecture for CMOS Based Image Acquisition

This paper describes a new co-processor architecture designed for CMOS sensor imaging. The co-processor unit is integrated into the image acquisition loop so as to exploit the full potential of CMOS selective access imaging technology. The processing features of the coprocessor are functional to the specific acquisition process of CMOS sensors (random region acquisition, variable image size, variable acquisition modes line/region based, multi-exposition images). Moreover, although built with pipelined or parallel HW processing modules, the co-processor architecture has been designed so as to obtain a unit that can be configured on the fly, in terms of type and number of chained processing, during the image acquisition process that is defined by the application. Simulated performances based on a FPGA implementation, are reported and compared to classical image acquisition systems based on PC platforms.
