Core-level dynamic voltage and frequency scaling in a chip multiprocessor

Abstract

Techniques described herein generally include methods and systems related to manufacturing a chip multiprocessor having multiple processor cores. An example method may include receiving performance or reliability information associated with each of the multiple processor cores, wherein the received performance or reliability information is determined prior to packaging of the chip multiprocessor, and storing the received performance or reliability information such that stored performance or reliability information is used to adjust an operating parameter of at least one of the multiple processor cores of the chip multiprocessor.

Description

Background technique [0001] Unless otherwise indicated herein, the approaches described in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section. [0002] Consistent with Moore's Law, the number of transistors that can feasibly be incorporated into an integrated circuit doubles approximately every two years. This trend has been going on for half a century and is expected to continue until at least 2015 or 2020. However, simply adding more transistors to a single-threaded processor no longer produces a significantly faster processor. Alternatively, increased system performance has been achieved by integrating multiple processor cores on a single chip to create a chip multiprocessor and sharing processes among the multiple processor cores of the chip multiprocessor. In addition, multiple processor cores of a chip processor can share other common system components, which can facilitate a lower cost and...
