Abstract :
A single-board 14.3-MOPS (million operations per second) video signal processor module (VSPM) has been developed. The module is fully microprogrammable and processes up to a 128 pel×128 pel subimage every 16.7 ms. Using a number of homogeneous VSPMs aligned in parallel, a real-time video signal processing environment is provided on the basis of an overlap-save or overlap-add technique. An experimental system has been constructed in order to demonstrate the signal processor approach´s effectiveness for video signals by implementing picture coding algorithms. Due to software control capability, various kinds of picture coding techniques can be evaluated by the system
