• 克服条件跳转指令缺陷,新一代超长指令字(VLIW)体系结构数字信号处理器(dsp)提供了条件执行指令支持

    As a conditional jump may cause significant code performance penalty, the architecture of recent VLIW DSPs offers support for conditional instructions.

  • 如果这些条件满足或者第二指令执行之前需要等待依赖项那么它们可以在单独周期执行

    If these conditions are not all met, or if the second instruction needs to wait for dependencies before issuing, then they are issued in separate cycles.

  • 意味着满足条件满足条件向量元素执行指令不同

    This means that vector elements which match the criteria go through a different set of instructions than those that do not.

  • 例如如果条件标上了likely”,那么编译可以代码True部分直接放在分支指令后面(这样需要执行分支指令)。

    For example, if the conditional is marked "likely" then the compiler can place the True portion of the code immediately following the branch (which will not be taken).

  • 另外循序执行方法是,程序遇到条件结果时,程序流程转送到指令部分

    An alternative to sequential execution transfers the program flow to another part of a script as a result of conditions that a script encounters.

  • 汇编语言执行算术指令跳转指令可以通过改变程序计数器执行条件语句循环语句。

    Assembly language instruction sequence perform arithmetic, and jump instruction by changing the program counter value to execute the conditional statement and circular statement.

  • 计算机程序反复执行一系列指令直到完成某一特定条件为止

    In computer programming, a process which repeats the same series of processing steps until a predetermined state or branch condition is reached.
