Abstract

The goal of the MOVIE VLSI chip is to facilitate the development of software-only solutions for real time video processing applications. This chip can be seen as a building block for SIMD arrays of processing elements and its architecture has been designed so as to facilitate high level language programming. The basic architecture building block associates a sub-array of computational processors with a I/O processor. A module can be seen as a small linear, systolic-like array of processing elements, connected at each end to the I/O processor. The module can communicate with its two nearest neighbors via two communication ports. The chip architecture also includes three 16-bit video ports. One important aspect in the programming environment is the C-stolic programming language. C-stolic is a C-like language augmented with parallel constructs which allow to differentiate between the array controller variables (scalar variables) and the local variables in the array structure (systolic variables). A statement operating on systolic variables implies a simultaneous execution on all the cells of the structure. Implementation examples of MOVIE-based architectures dealing with video compression algorithms are given.
