And hardware / software coverification is carried out to guarantee the correctness of design . in the design of hardware of memory system , according to the system specification , we select the appropriate memory capacity , sram block , associativity and the placement of cache in the pipeline 在存储系统的硬件设计中，始终以性能指标作为依据，克服了存储器容量、库单元规格选择、联合度的选择和cache在流水线中的位置选择等困难，设计出了符合指标要求的指令存储系统。
For example , because of the limit of their cmos chip performances and the capability of their memorizers , this kind of balancing instruments based on singlechip machine are not fit for large digital operations in signal processing , and have difficult in test faint signal of vibration , and their expansibility are not good 例如单片机类型的动平衡仪器，因其主芯片性能和存储器容量的限制，对于信号处理的大量数字运算能力不强，小振动信号的测试性能不佳，系统功能的可扩展性有限。
This thesis starts with the features and developing tendency of the recorder , and then discusses the realization of each functional parts of the little type paperless recorder , through a detailed introduction on its hardware and software structures , focusing mainly on the following innovative technologies : methods for banks switch , which makes the program running fluently on multi - roms 论文首先简要介绍了记录仪的发展历史，以及各阶段记录仪的性能比较，接着在介绍新型小长图无纸记录仪系统软硬件体系结构的基础上，对记录仪的各个功能部分的实现进行了讨论，其创新点主要有：单片机程序存储器容量扩展的实现，实现了多rom之间代码的流畅切换。
Because the mobile device contrasted by desktop has limited cpu power and memory , small screen and input device . at the mean time , wireless network has low bandwidth , low predictability and high latency . the origination of wireless application protocol ( wap ) would come to june 1997 这主要是因为现有的移动终端受其移动性和便携性的制约，与桌面机相比， cpu的主频及其计算能力都较小，存储器容量、显示屏和输入设备大小也受到限制，同时，无线数据网与有线网相比，带宽、连接可靠性及网络的可预测性都相对较低，网络延时大。
This software system of chip simulation ' s main function is simulate the main logic circue chips , 8088cpu , memory , registers , data _ bus , address _ bus , control _ bus and other chips . this function is based on the object - oriented technology , construct the chip object by the chip classes that we defined . . because this system need to simulate the detail function of computer hardware , so this system simulate the 8088cpu ' s order system , support the basic compile languages . one of the feture of this system is the simulation of a static memory , the room of the memory can be configured by testers from 1k to 64k 由于本系统在仿真过程中需要完全模拟计算机硬件的工作原理，因此本系统还仿真了8088cpu的基本指令系统，支持基本的汇编指令，在实验过程中可以由实验者输入相应的汇编指令以执行操作，并查看各芯片器件的引脚参数变化情况。本系统仿真的一个特点是动态仿真了存储器的大小，存储器容量可以由实验者根据需要自己设置，范围从1k到64k 。
On the basis of analysis to the research and design of the microbrowser , this article present a tight and distinct microbrowser ' s designing and realizing scheme , which restrcitly conform to the standard of wireless application protocol , furthermore , the scheme can adapat to the low main frequency and poor computation , limited storage capacity , small view screen and limited input device of mobile terminal 本论文在分析国内外微浏览器研究与设计的现状的基础上，根据移动终端主频、计算能力都比较小，存储器容量、显示屏和输入设备大小也受到限制的特点，基于无线应用协议标准的规定，提出了一种紧密、清晰的微浏览器的设计和实现方案。
