Abstract(in English) This paper describes major factor that affect power dissipation for dynamic sleep control. We analyzed factors through power analysis for a 32bit multiplier applying Run Time Power Gating(RTPG). This multiplier has a scheme to dynamically reduce the leakage power according to bit size of multiplied values. If one or both multiplied values have less than 16bit value, power gating is dynamically applied to the part of logic gates that need not to calculate output values. We design and implement this multiplier using ASPLA 90nm technology and analyze the leakage power. Experimental results show that this scheme enables to reduce the average leakage power of multiplier in circuit by up to 46% putting a part of multiplier into sleep at 85℃, however, It required approximately 20ns from he sleep start to the point at which leakage current in the multiplier circuit begins to reduce. Also it required approximately1.2us to achieve maximum leakage power reduction.
