|---|---|---|
This paper explores the benefits of splitting a monolithic power gate transistor into parallel, independently controlled, variable weighted power gates to provide programmable post-fabrication power grid resistance. This power gate topology creates energy saving opportunities by providing adjustable localized voltages during active modes and reducing leakage current in idle blocks while retaining data. Measurements show over 30% active energy savings per operation and 90% savings in idle current with retention. A modeling flow for a resistive power grid was also developed that demonstrates the effectiveness of this approach in a Bulldozer processor core. |
