Effects of building blocks on the performance of super-scalar architecture
Edil S. T. Fernandes, Fernando M.B. Barbosa · 1992
The inherent low level parallelism of Super-Scalar architectures plays an important role in the processing power provided by these machines: independent functional units promote opportunities for executing several machine operations simultaneously. From the viewpoint of the hardware designer it is very important to assess the influence of each functional unit, and the way they communicate, on the overall performance of the machine. Particularly, it is highly desirable to determine an upper bound in the number of additional functional units which give significant performance improvement ratios.
