The same can be done with if else instructions where the optimizer can order the if else so that either the if or else block is placed first depending on which block is more frequently true 可以对if / else指令执行相同的操作；这时，优化程序可以对if / else进行排序，根据哪个块为true的频率最高，将if块或者else块放在最前面。
It generates a single sql script file which can be used to recreate a database both schema and data in a shared hosting environment where the only connectivity to a server is through a web - based control panel with a script execution window 当伺服器的唯一连接是透过具有指令执行视窗的web控制台时，可以使用这项工具产生单一sql指令档，重新建立共用主控环境中的资料库结构描述和资料。
The data acquisition and processing card based on mcs - 51 is not so good to obtain good reputation for its high performance , reliability and flexibility because of its lower speed . so the board based on dsp and cpld is designed to substitute for it 采用mcs - 51系列cpu作为信号处理卡板载mcu也存在一些比较严重的问题，如cpu的指令执行速度慢，总线带宽窄等缺点，不能完成数据的高速处理。
The risc mcu core is based on harvard architecture with 14 - bit instruction length and 8 - bit data length and two - level instruction pipeline the performance of the risc mcu has been improved by replacing micro - program with direct logic block 设计的riscmcu采用14位字长指令总线和8位字长数据总线分离的harvard结构和二级指令流水设计，并使用硬布线逻辑代替微程序控制，加快了微控制器的速度，提高了指令执行效率。
Tms320vc5402 is a fixed - point digital signal processor , made by texas instruments incorporated , which is 16 - bit word length . vc5402 has enhanced harvard architecture built around one program bus , three data buses , and four address buses for increased performance and versatility 另外，采用mcs - 51系列cpu作为采集处理卡板载mcu也存在一些比较严重的问题，如cpu的指令执行速度慢，总线带宽窄等缺点，不能完成数据的高速处理。
Moreover , ck510 employs some low - power design techniques with performance improved . there are three instructions controlling power consumption on system - level and gated clock technique is widely used in ck510 . integer computing ability is very important for embedded cpu 在嵌入式处理器中，整数单元一般进行指令译码、指令发射和指令执行，是处理器中的一个重要部件，它直接影响着处理器的性能( cpi ，每条指令花费的时钟周期)和功耗指标。
Gridlock : a situation that can arise in a funds or securities transfer system in which the failure of some transfer instructions to be executed （ because the necessary funds or securities balances are unavailable ） prevents a substantial number of other instructions from other participants from being executed 死锁：在资金或证券转让系统中，由于一些转帐指令执行失败（因为没有足够的资金或证券余额）而阻碍其他参与者的大量其他指令的执行。
It is mentioned widely that cisc architecture has highly instruction consistency but risc architecture has efficiently instruction execute . on the design of the morden microcontroller , how to combine the two merit is one of the hotspots about the research of the system architecture 众多学者的研究表明， cisc结构有指令代码密度高的特点， risc结构有指令执行效率高的特点，在现代微控器设计中如何结合两者的优点，是系统结构研究的热点之一。
Many traditional optimizations such as register allocation optimizations are able to reduce the energy consumption indirectly while reducing the executed instructions . for instance , the improvements to the code generation techniques for the register stack can reduce the register saves and restores , further reduce the energy consumption and the execution delay 例如在itanium中,对栈寄存器分配的优化,可以减少rse ( registerstackengine )的溢出和填入操作,从而减少了处理器的等待时间,同时,降低了指令执行带来的功耗。
Based on analysis , we finished the architecture design and the division of the functional modules . allowing for the pic16c57 mcu can not suit the high speed situation , we improving the clock structure through using one clock instead of the original four clock technology . cooperating the instruction work step , the new clock structure executed one clock cycle per instruction 针对pic16c5x系列微控制器不能适用于高速场合的需要,对其时序结构进行了改进设计,用单时钟代替原来的四相时钟技术,采用二级流水结构,配合指令的工作节拍,使指令执行周期缩短为单个时钟周期。
