Abstract:
A circuit arrangement and method utilize a plurality of execution units having different power and performance characteristics and capabilities within a multithreaded processor core, and selectively route instructions having different performance requirements to different execution units based upon those performance requirements. As such, instructions that have high performance requirements, such as instructions associated with primary tasks or time sensitive tasks, can be routed to a higher performance execution unit to maximize performance when executing those instructions, while instructions that have low performance requirements, such as instructions associated with background tasks or non-time sensitive tasks, can be routed to a reduced power execution unit to reduce the power consumption (and associated heat generation) associated with executing those instructions.
Dynamic Merging Of Pipeline Stages In An Execution Pipeline To Reduce Power Consumption
A pipelined execution unit incorporates one or more low power modes that reduce power consumption by dynamically merging pipeline stages in an execution pipeline together with one another. In particular, the execution logic in successive pipeline stages in an execution pipeline may be dynamically merged together by setting one or more latches that are intermediate to such pipeline stages to a transparent state such that the output of the pipeline stage preceding such latches is passed to the subsequent pipeline stage during the same clock cycle so that both such pipeline stages effectively perform steps for the same instruction during each clock cycle. Then, with the selected pipeline stages merged, the power consumption of the execution pipeline can be reduced (e. g. , by reducing the clock frequency and/or operating voltage of the execution pipeline), often with minimal adverse impact on performance.

G06F 9/30
US Classification:
712214, 712E09016
Abstract:
A circuit arrangement and method utilize an issue rate-based predictive thermal management technique in a microprocessor or other integrated circuit that tracks the rate in which instructions are issued to one or more execution units in the processing unit, and selectively delays the issuance of subsequent instructions to the execution unit(s) based upon the tracked issue rate to predictively control the thermal output of the integrated circuit.

Abstract:
A method of manufacture for a medical electrical lead, and in particular, a method of manufacturing a sintered porous platinized electrode used in a steroid eluting pacing cardiac lead which offers increased dimensional and shape consistency over previously used manufacturing methods. The method of manufacturing the electrode consists primarily of mixing a conductive material and a binder to form a slurry, introducing a distal end of a substrate into a mold, creating a negative pressure in the mold, injecting the slurry into the mold to form a mass of conductive material on the substrate, and sintering the mold, substrate and conductive material to form an electrode.

Abstract:
A method of manufacturing a lead having an electrode includes the steps of introducing a substrate into a mold, creating a negative pressure in the mold, injecting a slurry comprising a binder and a conductive particulate material into the mold cavity during the step of creating negative pressure in the mold cavity, heating the mold having the substrate and the particulate material in an oven to cojoin the particulates and thereby form an electrode, removing the mold from the oven, removing the electrode from the mold, and assembling the electrode into a lead. The produced lead may be used as a steroid eluting pacing cardiac lead.
