A Combined Sensor Placement and Convex Optimization Approach for Thermal Management in 3D-MPSoC with Liquid Cooling

Giovanni De Micheli, David Atienza Alonso, Francesco Zanini

Modern high-performance processors employ thermal management systems, which rely on accurate readings of on-die thermal sensors. Systematic tools for analysis and determination of best allocation and placement of thermal sensors is therefore a highly relev ...

A Control Theory Approach for Thermal Balancing of MPSoC

Giovanni De Micheli, David Atienza Alonso, Francesco Zanini

Thermal balancing and reducing hot-spots are two important challenges facing the MPSoC designers. In this work, we model the thermal behavior of a MPSoC as a control theory problem which enables the design of an optimum frequency controller without dependi ...
