- All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle. 所有的寄存器都直接与算逻单元(ALU)相连接,使得一条指令可以在一个时钟周期内同时访问两个独立的寄存器。
- An action resulting from a single instruction. 执行命令由单一指令而引起的操作
- single instruction execution 单指令执行
- A single instruction can stop the machine. 一条简单的指令可以使机器停开。
- GPU uses SIMD (Single Instruction Multiple Data) technology. 图形处理器使用多流单指令数据流扩展指令集技术。
- In other words, software interrupts always occur at the beginning of an instruction execution cycle. 换句话说,软体中断常常在指令运行周期的开始发生。
- single instruction execute mode 单指令执行方式
- Problems in the application of pipeline structures for CISC, such as irregular instruction set and long cycle of instruction execution, are discussed. 重点讨论了流水线技术在80C51这类CISC中的一些应用问题(如指令格式不规范、执行周期长等)及其解决办法。
- A single instruction in programming language that results in a series of instructions in machine language. 宏指令计算机编程语言中可以在机器语言中形成一系列指令的命令
- In the instruction execution pipeline stage, scalable pipeline technology was adopted to realize the video processing instruction. 为有效实现扩展指令,处理器执行级采用了可扩展流水级技术。
- In Chapter 2, we learned that the processor fetches and executes a single instruction during each machine cycle. 在第二章中,读者知道了在每个机器周期内处理器取出并执行一条指令。
- Many embedded applications have little or no need for floating-point arithmetic, and software emulation of PowerPC floating-point instruction execution is usually more than adequate when it is needed. 很多嵌入式应用程序很少或者根本不需要浮点算法,而当需要的时候,对PowerPC浮点指令执行进行软件仿真就足够了。
- In computer programming,the part of a computer program,in some casesa single instruction or an address,which passes control and parameters between separate portions of the computer program. 计算机程序设计中,用于在程序的不同部分之间传递控制权和参数的程序部分,某些情况下,它是一条指令或一个地址。
- In order to further enhance the speed of codec for achieving real-time coding, this thesis introduces multimedia instruction collection such as MMX, SSE, SSE2 as well as SSE3 based on SIMD (Single Instruction Multi Data). 为了进一步提高编解码速度以达到实时编解码;又引入了Intel的MMX、SSE、SSE2以及SSE3等基于SIMD(单指令多数据)技术的多媒体指令集;并利用这些指令集对H.
- privileged instruction execution [计] 特许指令执行
- In computer programming, the part of a computer program, in some casesa single instruction or an address, which passes control and parameters between separate portions of the computer program. 计算机程序设计中,用于在程序的不同部分之间传递控制权和参数的程序部分,某些情况下,它是一条指令或一个地址。
- Average Instruction Execution Time 平均指令执行时间
- A facility that permits a programmer to selectively list single instructions or short segments of code during compilation. 一种设施,允许程序员在编译期间有选择地列出一些单独指令或短程序段。
- When the IN instruction executes, the IBF bit is cleared and the data in the port are moved into AL. 当IN指令执行时,IBF位被清除,并且端口内的数据被送入AL。
- The LOCK instruction prefix locks out all other CPUs while the microcode for the current instruction executes, thereby guaranteeing data integrity. 在当前指令的微代码执行的时候,LOCK指令前缀把所有其他CPU关在外面,因此保证数据完整。
