Abstract :
The paper describes the architecture of an image coprocessor based on a linear array of elementary processors. The system has been designed for real-time vision applications and embeds a direct I/O interface to a camera device. The instruction set of the elementary processors is based on morphological match operators on a reduced 5×5 neighborhood. Two additional communication mechanisms, one fixed and one programmable, provide both global and multiple communication channels among processing elements which are not directly connected
