摘要： An asymmetric multiprocessor system (ASMP) may comprise computational cores implementing different instruction set architectures and having different power requirements. Program code executing on the ASMP is analyzed by a binary analysis unit to determine what functions are called by the program code and select which of the cores are to execute the program code, or a code segment thereof. Selection may be made to provide for native execution of the program code, to minimize power consumption, and so forth. Control operations based on this selection may then be inserted into the program code, forming instrumented program code. The instrumented program code is then executed by the ASMP.

摘要： An asymmetric multiprocessor system (ASMP) may comprise computational cores implementing different instruction set architectures and having different power requirements. Program code for execution on the ASMP is analyzed and a determination is made as to whether to allow the program code, or a code segment thereof to execute on a first core natively or to use binary translation on the code and execute the translated code on a second core which consumes less power than the first core during execution.

摘要： Detecting a static graphic object (such as a logo, title, or sub-title) in a sequence of video frames may be accomplished by analyzing each selected one of a plurality of pixels in a video frame of the sequence of video frames. Basic conditions for the selected pixel may be tested to determine whether the selected pixel is a static pixel. When the selected pixel is a static pixel, a static similarity measure and a forward motion similarity measure may be determined for the selected pixel. A temporal score for the selected pixel may be determined based at least in part on the similarity measures. Finally, a static graphic object decision for the selected pixel may be made based at least in part on the temporal score.

摘要： Technologies for binary loop trip count computation include a computing device that dynamically instruments binary code, executes the instrumented code, and records execution statistics during execution of the instrumented code. The computing device may instrument only instructions affecting local control flow within functions of the binary code. The computing device may combine execution statistics from multiple threads or process instances of the binary code. After completing execution of the instrumented code, the computing device generates a control flow graph indicative of control flow of the binary code and recursively detects binary loops within the binary code. The computing device calculates a trip count for reach detected binary loop using the recorded execution statistics. Other embodiments are described and claimed.
