为克服条件跳转指令的缺陷,新一代超长指令字(VLIW)体系结构的数字信号处理器(dsp)提供了对条件执行指令的支持。
As a conditional jump may cause significant code performance penalty, the architecture of recent VLIW DSPs offers support for conditional instructions.
如果这些条件不都满足,或者第二条指令在执行之前需要等待依赖项,那么它们可以在单独的周期中执行。
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.
这意味着满足条件的与不满足条件的向量元素执行的指令集不同。
This means that vector elements which match the criteria go through a different set of instructions than those that do not.
