ADDRESS GENERATING DEVICE AND MOVING VECTOR DETECTING DEVICE

摘要

A high-function address generating apparatus is realized which generates a memory address that can access a multidimensional area without running over a memory area specified by a user. Continuous addressing domain which is determined by a top address and a final address is set by an addressing domain setting means 101, an address is generated by a two-dimensional address generating means 106, the address in a two-dimensional area is compared with the final address and the top address by a first and a second comparing means 108 and 109, respectively, whether it run over the addressing domain or not is judged by an address correction means 112, and an address running over is corrected so as not to run over.
