Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: In a 64-bit processor, many of the data values actually used in computations require much narror data-widths. In this study,  demonstrate that instruction data-widths exhibit very strong temporal locality and describe mechanisms to accurately predict data-widths. To exploit the predictability of data-widths,  propose a Multi-Bit-Width (MBW) microarchitecture which, when the opportunity arises, takes the wires normally used to route the operands and bypass the result of a 64-bit instruction, and instead uses them for multiple narrow-width instructions. This technique increases the effective issue width without adding many additional wires by reusing, already existing datapaths. Compared to a traditional four-wide superscalar processor our best MBW configuration with a peak issue rate of eight IPC achieves a 7.1% speedup on the simulated SPECint2000 benchmarks, which performs very ll when compared to a 7.9% speedup attainable by a processor with a perfect data-width predictor.
