In order to enhance the performance of a computer, most modern processors use superscalar architecture and raise the clock frequency. Superscalar architecture can execute more than one instruction per each cycle. The amount of instruction level parallelism will become more and more important when superscalar issue is increased. In some schemes [6, 14], instructions can be speculatively waked up. The more instructions are waked up, the more ILP is exploited, hence IPC is increased. We can adopt the speculative aspect to wakeup more instructions. But the ILP is still limited by the true data...
