The part of execution in which an operand or instruction is read from main stora ge and written into a control unit or arithmetic unit register 执行过程中的一个阶段所需的时间,在此期间,计算机从主存储器中取出指令或操作数,并将其存入控制器或运算器的寄存器中。
In modern vlsi technology , hundreds of thousands of arithmetic units fit on a 1cm 2 chip . the challenge is supplying them with instructions and data . stream architecture is able to solve the problem well 在摩尔定律作用下,在单芯片上可集成的晶体管数快速增长,单芯片拥有成百上千的运算单元不再是问题,关键是如何给如此多的alu提供足够的指令和数据。
3 - d graphics on mobile phones is quite similar to 3 - d graphics on pc in years past . there is no hardware acceleration , and processor speeds are quite low , and there also is the lack of floating point arithmetic unit in mobile phones 因此论文从通用的部分开始论述,然后明了移动平台的特征,并试图解释三维引擎的一般原理和设计一个具有粗适性的基于游戏的三维图形引擎。
