— This paper presents the design of a model-based nonlinear observer of an evaporator (a two-phase flow heat exchanger) for advanced dynamic control of air conditioning and refrigeration systems. A control-oriented, low-order model is derived for the evaporator. Based on sensor measurements of the evaporating temperature, the nonlinear observer can be used(More)
For the stream-like applications with high-bandwidth and low latency, optimizing the memory latency can effectively improve the QoS. In this paper, we propose a dedicated adaptive loop pre-fetch mechanism to reduce the memory latency and also improve the pre-fetch accuracy. In the mechanism, when a loop sequences is detected, the stream pre-fetch engine can(More)
