A single-board video signal processor module employing newly developed LSI devices

摘要

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.
