Abstract

Clockless implementations dramatically improve energy efficiency without requiring more area than conventional synchronous circuit designs. The clockless ARM996HS, developed through the TiDE design flow, consumes about one-third the power of comparable synchronous, clock-gated, ARM cores implementing the same ISA. The ARM996HS also generates low peak currents and produces very low electromagnetic emissions, and it is robust against variations in current, voltage, and temperature.
