Abstract:

 By using HillMarty′s deduction of speedup 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 multicore more optimal than that of the homogeneous multicore. Two cases are dsicussed: one is that the more powerful core in the heterogeneous multicore processors and the core in the homogeneous multicore processors are the same, and the other is that the less powerful core in the heterogeneous multicore processors and the core in the homogeneous multicore processors are the same. Therefore, the best design solutions of the heterogeneous multicore can be provided.
