Abstract
The multi-core processor integrates multiple processor cores on a single chip which can execute multiple threads si- muhaneously, Although the clock frequency of each processor does not increase any more, the computation which is provided by parallel procession of multiple processors is more powerful than that of single processor, design complexity of CPU promotes radically at the same time. Based on design technologies of modem processor, this paper investigates several methods to opti- mize program performance by combination with implementation procedure of program; therefore, they can enhance the quality of programming and improve execution efficiency.关键词
