An efficient multi-window display-memory architecture for full-motion video signals

A new architecture is proposed that drastically reduces the memory requirements for full motion video processing functions such as scan-conversions source synchronization and zooming for multiple video input sources. It has a simple modular structure which incorporate a few inexpensive DRAMs with a total storage capacity of one single video-frame. Reduction of memory capacity and real-time processing power is achieved by computing (off-line) an efficient schedule for all memory-access requests associated with a specific window configuration. This schedule is then instantly compiled into micro-programs which are down-loaded into the real-time controllers of the architecture
