Abstract: Methods for modifying power use of a semiconductor device include receiving, at one or more processors, an activity stream of a simulation of a semiconductor device, the activity stream comprising a stream of signals. Using the one or more processors, integrated circuit actions are recognized from the activity stream, each integrated circuit action representing an abstraction of work done by the semiconductor device. The processor(s) determine one or more values associated with the integrated circuit actions. A model of power use is generated for the semiconductor device, the model based at least in part on the recognized integrated circuit actions and the associated values. Based on an output of the model, power use of the semiconductor device is modified. Other methods and systems related to determining, modeling, and predicting power/energy use of semiconductor devices are also disclosed.

Abstract: Methods, systems, and articles of manufacture consistent with the present invention optimize allocation of items to a stack memory instead of a heap memory. It is determined whether an item to be placed on the heap memory escapes from the scope of the item's allocator, and whether the item survives the item's allocator. The item is allocated to the stack memory responsive to the item not escaping from the scope of the item's allocator and not surviving the item's allocator.

Abstract: Improved techniques for reducing the size of compiler products are disclosed. The techniques facilitate reduction of size by providing differential schemes aimed at producing compiler related information in a compressed form. The compressed compiler related information include symbol names associated with symbols encountered in programming languages. The improved techniques yield improved compilation times and compiler products that utilize substantially less storage space (e.g., disk storage space).

Abstract: Improved techniques for reducing the time and cost associated with producing compiler products are disclosed. A programming system including an enhanced compiler suitable for compilation of source programs is disclosed. The enhanced compiler can be used to compile source programs so that template (or generic) instances already available from the libraries are not recreated. The enhanced compiler can efficiently compile a request to create an instance by determining whether the instance is already available in one of the libraries. If the instance is already available from one of the libraries, the instance need not be created. In comparison with conventional models, the enhanced compiler can access libraries directly without requiring a significant amount of preparatory work and/or costly operations such as preparation of options files and transformation of instance names to linker symbol names. As a result, the enhanced compiler is more efficient (faster) than convention compilers.
