It aims at reducing the number of execution cycles of instructions , and has experienced from the period of single issue architecture to the period of multiple issue architecture . in the past twenty years , risc has become more and more mature abroad . it makes great sense to develop our own risc and it is a effective way to develop our own risc with the instruction set which is compatible with those of risc which has been widely used 80年代初出现的risc技术是计算机体系结构的重大变革，它以减少指令执行的平均周期数为结构设计的主要目标，经历了从单发射结构到多发射结构的演变过程，解决了深度流水技术、相关技术、转移预测技术、编译优化技术等一系列技术难点，在20多年的时间里， risc技术的发展已日趋成熟与完善微处理器在军事和民用领域都有着广泛的应用，研制具有我国自主独立版权的微处理器在当今具有重大意义。
As to the change of trading techonogies , most markets have evovled from floor trading to electronic trading . among different markets , electronic trading have penetrated most comprehensively in the stock market . as to the trading process , electronic trading has prevaded in the pre - and post - trade information dissemination , order transmission and execution , settlements , etc . in 1990 ' s , internet has altered the traditional operation model of securities trading , which mainly includes the trading services on internet , internet dpo and alternative trading systems 从交易技术变迁的角度看，大多数证券市场都经历了从人工交易演变为电子交易的过程；从不同证券市场来看，电子交易在股票市场发展最为深入，但固定收益证券市场和衍生品市场电子交易的发展势头也非常迅猛；从证券交易过程来看，电子交易已渗透至交易信息披露、指令传递与指令执行、清算交割等环节。
Although gpu has a very high computing speed , algorithms implemented in cpu cannot be put to execute in gpu directly because of the discrepancy in instruction execution manner of the two . gpu ' s architecture is a high parallel simd instruction set system . to reimplement algorithms insufficient to run on cpu with programmable graphics hardware , it has to reconsider the data structures and procedures to implement them to make full use of the 虽然gpu具有非常高的计算速度,但并不能将以前在cpu中实现的算法直接放到gpu中来执行,这是因为gpu的指令执行方式和cpu不一样, gpu的体系结构是一种高度并行的单指令多数据( simd )指令执行体系,所以要在可编程图形硬件上实现在cpu中效率不高的算法,就需要重新制定算法实现的数据结构和步骤,以充分利用gpu并行处理体系结构带来的性能优势。
The software adopts three kind of control mode to start up the data acquisition system , it ensures reliability of the acquisition system . the control system communicates with the shipborne support system adopting broadcast when down and timing when up , and requires return for the remote instructions , so it ensures the communications of the five bouys with the control and acoustic emission vessel . this software is based on assemble language of mcs51 , it is held in the eprom in mcu 控制和通信软件采用设定采集时间表、外推采集与启动采集三种方式控制采集系统，可靠地保证了远程、无人值守浮标在长时间、连续工作情况下数据采集的很高的可靠性；控制和通信软件采用下行广播、上行时分的工作哈尔滨工程大学硕士学位论文方式实现各浮标与船载分系统间的通信，且无线电遥控指令执行反馈，可靠地保证了浮标与船载分系统间的通信。
Then , by programming with c + + , this thesis achieved partly some application examples of remote control network system which are based on this research , including main program module which took charge of initializing system and remote waking up the console of the controlled and getting the hardware information of the controlled , directive text information setup module which took charge of transmitting text and data , command execution module which took charge of executing simple control command , real time oversight module which took charge of transmitting the real time video of the console of the controlled and feeding information back to the console in charge 之后本文利用c + +编写程序，来实现部分基于本研究的远程控制系统中的一些应用实例，采用了模块化程序设计，实现了负责系统的初始化、并远程唤醒对方控制台、获取对方的硬件信息等功能的主控程序模块，完成系统文本信息、数据的传输功能的指令文本信息设置模块，执行简单的控制指令功能的控制指令执行模块，传输对方控制台即时运行画面并将信息反馈给控制端的功能的即时监控模块。
