On instruction windowing for fine grain parallelism in high-performance processors
1993
Fine grain parallelism is an effective approach to enhancing processor performance through multiple and possibly out of order instruction issue and execution. The authors define, design and evaluate a basic central window, which works with a dynamic instruction stream. Several schemes are presented to reduce the window's potential impact on processor cycle time and its hardware cost. It is shown that a central window can function effectively as a buffer for speculative execution and for handling interrupts and exceptions. >
