For years, processor makers consistently delivered increases in clock rates and instruction-level parallelism, so that single-threaded code executed faster on newer processors with no modification.

多年来，处理器制造厂商在不断提高时钟速度和指令级并行性，因此单线程代码不需要修改就可在新的处理器上更快运行。

However, this technique also increases the register pressure while it takes advantage of the instruction-level parallelism, and the register spilling is an effective approach to solve this problem.

但该技术在提高指令并行性的同时也增加了寄存器压力，而寄存器溢出技术正是解决寄存器压力的有效方法。

Several basic blocks could be merged into a hyperblock in predicated execution so that instructions could be scheduled on a larger scope and more instruction level parallelism could be extracted.

谓词执行技术能够将多个基本块合并为一个超块，扩大指令调度范围，开发更多的指令级并行。
