| Research Abstract |
Modern microprocessors achieve high performance by executing multiple instructions in parallel. In this research, we have introduced a new execution model where instructions in a local critical path are statically found at the compile time, and only the instruction steering is dynamically performed at execution time. From the performance evaluations, we have shown that the IPC of our execution model is comparable to that of existing models, even in the case of no dynamic steering.
