help solve the &quot

Cheap Womens NBA Jerseys increase in the speed of computer is not only related with the processor performance, also need to solve the memory of "memory wall problem". Professor Sun Xianhe the dean of Computer Department of Illinois Institute of Technology American Chinese scientist, recently proposed a new mathematical model, can greatly improve the data read speed, help solve the "data processing and analysis problem facing big data era".

usually think that the processor is the main obstacle to improve the calculation speed of computers, but memory performance if not also control the speed of calculation. Sun Xianhe said, the Cheap Raptors Jerseys past 40 years, Moore's law growth speed of computer processors have followed the evolution of semiconductor technology, converted into each year to speed up 52%. However, the memory of the computer operation speed of only 9% a year, the average annual performance of hard disk speed of only 6%. Now the operating speed of computer memory only processor speed about one in 400, which led to the access time, the formation of "memory wall".

in Sun Xian and in 1990 proposed a "memory constraint speedup laws". In the law basis, Sun Xian and recently proposed a mathematical model called C-AMAT, through parallel memory read mode, the parallel processing computer cache and memory system, can greatly reduce the computer read in terms of delay in the data, have the computer read the speed can be increased by 100 times. The results will be in the America Institute of electrical and Electronics Engineers Computer Society (IEEE) published Cheap Heat Jerseys in professional journals "subordinate computer".

Sun Xianhe said: "this is the design of data centric, while the previous design are calculated as the center, C-AMAT Cheap 76ers Jerseys model represents a fundamental change in a design."

professor of University of Chicago, former Intel Cheap Bobcats Jerseys vice president of research money Anderson said, whether it is a smart mobile phone or super computer, the main obstacle to computing performance focused on mobile data, mathematical model of C-AMAT touches the key problem, is of great significance to better improve software and hardware design.
