A system, method and computer program product are provided for conditionally eliminating a memory read request. In use, a memory read request is identified. Additionally, it is determined whether the memory read request is an unnecessary memory read request. Further, the memory read request is conditionally eliminated, based on the determination.

System, method, and computer program product for conditionally eliminating a memory read request

Disclosed below are representative embodiments of methods, apparatus, and systems for performing power analysis during the design and verification of a circuit. Certain exemplary embodiments include user interfaces and software infrastructures that provide a flexible and powerful environment for performing power analysis. For example, embodiments of the disclosed technology can be used to construct complex and targeted power queries that quickly provide a designer with power information during a circuit design process. The disclosed methods can be implemented by a software tool (e.g., a power analysis tool or other EDA tool) that computes and reports power characteristics in a circuit design (e.g., a system-on-a-chip design or other integrated design).

Flexible power query interfaces and infrastructures

Disclosed herein are representative embodiments of methods, apparatus, and systems for analyzing and/or transforming code (typically, source code) to reduce or avoid redundant or unnecessary power usage (e.g., power cycling, resource leak bugs, and/or unnecessarily repeated activity) in the device that will ultimately execute the application defined by the source code. The disclosed methods can be implemented by a software tool (e.g., a static program analysis tool or EDA analysis tool) that analyzes and/or transforms source code for a software application to help improve the performance of the software application on the target device. The disclosed methods, apparatus, and systems should not be construed as limiting in any way.

Modifying code to reduce redundant or unnecessary power usage

An integrated circuit design system, method, and computer program product are provided that takes into account signal stability. In use, at least one condition is identified where an output of a logic element before receipt of a clock signal is the same as the output of the logic element after receipt of the clock signal. To this end, such logic element may be disabled based on the identified condition for power savings or other purposes.

Integrated circuit design system, method, and computer program product that takes into account the stability of various design signals

An integrated circuit design system, method, and computer program product are provided that takes into account observability based clock gating conditions. In use, at least one condition is identified where an output of a first logic element is not a function of a first input of the first logic element, due to a second input of the first logic element. To this end, at least one second logic element may be disabled based on the identified condition for power savings or other purposes.
