Valid Digit and Overflow Information to Reduce Energy Dissipation of Functional Units in General Purpose Processors
Summary :
In order to reduce the dynamic energy dissipation in CMOS LSIs, it is effective to reduce the frequency of value changes of the signals. In this paper, a data expression with the valid digit and lower digit overflow information is proposed to suppress unnecessary signal changes in integer functional units and registers of general purpose processors. Experimental results show that the proposed method reduces the energy dissipation by 9.8% for benchmark programs.
