Pattern recognizing processor

Abstract

Abstract PURPOSE:To effectively recognize a pattern by applying a highly efficient pipeline process and a parallel process to perform a space filtering operation, a matrix arithmetic operation, etc., at a high speed. CONSTITUTION:A 2-port memory 10 is prepared together with a dictionary memory 11, a shift arithmetic part 12, an ALU13, and a multiplier/adder 14 respectively in a module. These module elements are actuated in a pipeline process so that the space filtering and matrix arithmetic operations are processes at a high speed with use of the parallelism. Therefore the memory 10 can carry out the reading and writing operations independently of each other. Thus a memory access never bottlenecks the processing speed even though the data receiving the frequent accesses are stored in the memory 10. Furthermore the part 12 performs a normal barrel shift and also segments a noted and nearby picture elements out of a binary picture. In such a constitution, a pattern is recognized with high efficiency.
