By using HillMarty′s deduction of speedup ratio(It does not take into the chip resources expended on shared caches, interconnection networks, and memory controllers), the structure of BCE′s distribution is obtained which make the performance of the heterogeneous multicore more optimal than that of the homogeneous multicore. Two cases are dsicussed: one is that the more powerful core in the heterogeneous multicore processors and the core in the homogeneous multicore processors are the same, and the other is that the less powerful core in the heterogeneous multicore processors and the core in the homogeneous multicore processors are the same. Therefore, the best design solutions of the heterogeneous multicore can be provided.
