MULTI-PLANE VIDEO RAM CONSTITUTING SYSTEM

摘要

PURPOSE:To obtain a high function by the small number of input terminals and a simple constitution by arranging a memory array three-dimensionally, allowing the memory array to be three-dimensionally accessed and allowing the titled system to include a multi-plane bit arithmetic part to execute drawing processing in its inside. CONSTITUTION:The titled system consists of a multi-plane bit arithmetic part 1 for executing arithmetic processing corresponding to input data inputted from the external and memory arrays 2-0-2-3 constituted by arraying memory planes consisting of m lines and n rows three-dimensionally by k groups so as to access the same position of the memory planes in order to write the processed result by the computing part 1. The arithmetic processing of input data inputted from the external is executed in accordance with a prescribed rule specified by input information previously applied from the external and the processed result is written in the same positions as the k memory arrays 2-0-2-3. Consequently, drawing with a high function can be attained by the small number of parallel accessing I/O terminals.
