In this paper, the performance of multicore processor architecture is analyzed which utilizes out-of-order superscalar processor core using multiple basic block execution. Using SPEC 2000 benchmarks as input, the trace-driven simulation has been performed for the out-of-order superscalar processor with the window size from 32 to 64 and the number of cores between 1 and 16, exploiting multiple basic block execution from 1 to 4 extensively. As a result, the multicore out-of-order superscalar processor with 4 basic block execution achieves 22.0 % average performance increase over the same architecture with the single basic block execution.
