Abstract

This paper describes a new architecture for a cellular processor array integrated circuit, which operates in both discrete- and continuous-time domains. Asynchronous propagation networks, enabling trigger-wave operations, distance transform calculation, and long-distance inter-processor communication, are embedded in an SIMD processor array. The proposed approach results in an architecture that is efficient in implementing both local and global image processing algorithms
