The multiply clock domain (MCD) technique is a novel technique to compromising between synchronous systems and asynchronous systems to reduce the power. However, most present studies of MCD are based on superscalar architectures. In this paper, MCDE, a MCD technique based on explicitly parallel instruction computing (EPIC) architecture is designed and implemented to reduce the power of clock distribution network. In addition, a series of experiments have been done to evaluate it. The result of the experiments show that, using a MCDE clock network microarchitecture with a fine-grained adaptive dynamic adjustment algorithm, can effectively decrease the microprocessor power by 40%, compared with the original EPIC clock network microarchitecture.
