Abstract :
Heterogeneous multi-core processors have strong potential for performance improvement, energy efficiency and area efficiency, compared to the homogeneous multi-core processors. The present methods of execution migration for heterogeneous multi-core processor suffer in efficiency, cost, compatibility, or programmability. In this paper, we propose a HW/SW code sign migration method based on binary-instrumentation. Our method takes full advantage of the shared-ISA. It enhances the performance of heterogeneous chip multiprocessor with low HW/SW cost. And it´s not required to modify source codes or compile system. The experiment results show that the efficiency of our method is 3.29 times of kernel simulation.
