Abstract

The DSP architecture PRISMA for object-based video signal processing is presented in this paper. Considering the specific hardware requirements of object-based algorithms a parallel architecture has been developed, which consists of 8 programmable data paths. To utilize the processing power provided by these data paths, a new controlling scheme is employed by the PRISMA processor. This dynamic associative controlling distributes 3 independent instruction streams to the 8 data paths and comprises the advantages of alternative controlling approaches, like SIMD and MIMD. It allows an efficient execution of data-dependent operations as well as a flexible partitioning of the processing resources at runtime, which is advantageous for parallel processing of concurrent objects with different performance requirements.
