Subject: | [Gems-users] link power in orion 2.0 |
Hi, I tried to use orion 2.0 to get more accurate link power and link area. The leakage and dynamic link power is calculated as following: Pleakage = LinkLeakagePowerPerMeter(link_len_in_m, Vdd) * link_len_in_m * data_width; Pdynamic = 0.5 * load * LinkDynamicEnergyPerBitPerMeter(link_len_in_m, Vdd) * freq * link_len_in_m * (double)data_width; where the link_len_in_m represents the link length (in meter). I think the load should be passed by Garnet and I calculated the load as following: double sim_cycles = (double) (g_eventQueue_ptr->getTime() - m_net_ptr->getRubyStartTime()); load = (double) (m_link_utilized)/ sim_cycles; where the m_link_utilized is a member of class Link_d from garnet which I think represents link utilisation. I'm not sure whether this calculating is right or not. Would anyone give me some hints? Thanks a million! -- Regards Qi Zuo School Of Computer Science and Technology Beijng Institute of Technology, China, 100081 |
