METHOD AND EQUIPMENT FOR OPTIMIZING ADDRESS MAP IN MULTISCALAR EXPANSION

摘要

PROBLEM TO BE SOLVED: To provide a system and a method, for optimizing an address map in multithread processing environment such as multiscalar expansion of a processor supporting a SIMD process. SOLUTION: A disclosed shared memory 120 is used for multithread-processing a single instruction multidata thread (SIMD) and a multiscalar thread without conflict of an internal thread memory area, and to enable transition to a multiscalar mode from a SIMD mode. A memory area of the shared memory 120 is address-mapped such that the memory area is zigzag-arranged. COPYRIGHT: (C)2006,JPO&NCIPI
