给出热阻矩阵的表达式,研究三维单芯片多处理器(3D CMP,three-dimensional chip-multiprocessor)的温度特性,通过Matlab分析热容、热阻和功耗对温度的影响.结果表明:减小热阻和功耗可以有效约束3D CMP的稳态温度;热容增大可以导致3D CMP温度上升时间变长,但不影响其最终稳态温度.
An expression of thermal resistance matrix is given.Transient temperature characteristics of three-dimensional chip-multiprocessors(3D CMP) are studied.Effect of heat capacity,thermal resistance and power consumption on temperature is analyzed.It shows that steady temperature of 3D CMP is limited effectively by reducing thermal resistance and power consumption.Heat capacity influences rise time of temperature.It does not affect steady temperature.
