The Dual Mode Logic (DML) defines run-time adaptive digital architectures that switch to either improved performance or lower energy consumption as a function of actual computational workload. This flexibility is demonstrated for the first time by silicon measurements on a 16x16-bit Booth multiplier fabricated as a part of an ultra-low power digital signal processing (DSP) architecture for 16-nm FinFET technology. When running in the full-speed mode, the DML multiplier can achieve a performance boost of 19.5% as compared to the equivalent standard CMOS design. The same design saves precious energy (-27%, on average) when the energy-efficient mode is enabled, while occupying 13% less silicon area.

Abstract
The Dual Mode Logic (DML) defines run-time adaptive digital architectures that switch to either improved performance or lower energy consumption as a function of actual computational workload. This flexibility is demonstrated for the first time by silicon measurements on a 16x16-bit Booth multiplier fabricated as a part of an ultra-low power digital signal processing (DSP) architecture for 16-nm FinFET technology. When running in the full-speed mode, the DML multiplier can achieve a performance boost of 19.5% as compared to the equivalent standard CMOS design. The same design saves precious energy (-27%, on average) when the energy-efficient mode is enabled, while occupying 13% less silicon area.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
