Abstract
Performance enhancement has always been a primary design goal for designers. Modern automation technology demands for reliable low cost controllers, required for specific applications. The restricted resources limits the number of functional units available on a processor which results into lowered performance. The better performance can be achieved with splitting existing functional unit into smaller independent units. The split of arithmetic and logic unit into two independent units namely arithmetic unit and logic unit, provides the facility for simultaneous operation by both of the units. This results into lesser execution time. The simulator Simplescalar has been modified to simulate split ALU. The benchmarks are run in order to collect performance statistics. The simulation parameters, including execution time have been recorded for standard simulator having integral ALU unit, and for split ALU unit and further compared to show enhanced performance with split ALU.
