SIGNAL PROCESSING APPARATUS AND METHOD FOR PROCESSING MULTI-DIMENSIONAL SIGNALS, AND COMPUTER-READABLE MEDIUM

摘要

A signal processing apparatus and method for processing N-dimensional signals where N is an integer not smaller than 4 are disclosed. The signal processing apparatus includes a memory unit that stores reference values corresponding to combinations of each component of the N-dimensional signals; the memory unit has (M+1)×2N−M sub-memories which respectively store each part of the reference values divided into (M+1)×2N−M, where M is an integer smaller than N. A reading unit reads the reference values from the memory unit.
