摘要： A system, method, and computer program for analyzing code execution and software performance characteristics are disclosed. Samples of code during run-time or from crash logs can be displayed as both a top-down tree of calls from a particular function and a bottom-up tree of calls to the particular function. Data mining techniques, including filtering and focusing, remove code that is not of interest and display code that is more relevant to performance analysis. In particular, functions contained in libraries such as system libraries can be stripped from view. The cost associated with an excluded function can be propagated to a calling function, in either the top-down or bottom-up tree.

摘要： To reduce the size of binary decision tree-type integrated circuit representations of boolean expressions, any boolean expression or sub-expression which is fully defined by one of its partial expressions is represented by only that one partial expression. If gate branching of the decision tree is a default case which is invoked only when both partial expressions are needed to define an expression or sub-expression. These reduced size expression trees readily map into CMOS cascade logic, thereby producing low power, reasonably compact, integrated circuit representations of boolean expressions.
