Abstract

In this paper we present a new hardware design of an image processing system by using a dedicated image processor. The system consists of an integrated 2D convolver which performs a 2D convolution between the pixels present within a video window and a set of stored coefficients which are programmable. Two area sensors are used for color image acquisition and applications. Specialized memories (dual-port static RAM and SyncFIFO), have been used between the host machine (IBM AT) and the video A/D converter (VADC) respectively. The system is very flexible in the sense that the supporting logic can be programmed even in the midst of their operation, thus analyzing images in real-time. Some characteristics of the systems are: (1) a 3 X 3 convolution of a 512 X 512 8-bit image is carried out in 1.88 sec, (2) clock speed of up to 40 MHz is possible, (3) number of allowed cascaded processors is 16. The design is a partial solution to the image processing applications.
