Improvement of microsystem throughput using new cooling system

Abstract

This paper presents a new possibility of clock frequency/voltage control in microsystems i.e. high performance processors, exploiting information about cooling efficiency. In this paper, we propose an approach that better exploits the thermal abilities of a chip fixed to cooling system in order to eliminate its energy accumulation. For the purpose of the proposed method, the calculation of so called time shift (TS) is introduced. TS is defined as the duration where the computational system can perform the task at higher frequency without any thermal violation when the chip temperature is close to critical thermal threshold. The analogy between thermal and electrical parameters allows to model RC thermal compact model of structure (chip fixed to the cooling system). Based on this assumption, the authors compute the TS value versus different parameters using RC thermal compact model in Spice environment. The results indicate that TS could fulfil a significant part of die total working time. As an effect the proposed approach may be a means for increasing average clock frequency or voltage supply, consequently enhancing the system’s throughput.
