A hierarchical multi-core debugger interface is described that is configured to enable debugging of a multi-core device. In some implementations, a multi-core debugger renders core-specific user interface components with a core-specific visual characteristic in the hierarchical multi-core debugger interface. In other implementations, the multi-core debugger renders core-specific user interface components in core-specific windows in the hierarchical multi-core debugger interface. In still other implementations, the multi-core debugger renders core-specific user interface components in core-specific windows in the hierarchical multi-core debugger interface, where each core-specific window is displayed with a core-specific visual characteristic.

Hierarchical multi-core debugger interface

Systems, methods, and other embodiments associated with echo cancellation are described. According to one embodiment, an apparatus includes a plurality of first registers configured to respectively store information related to a performance of a processor and a second register in communication with each of the plurality of first registers. The apparatus also includes logic configured to detect a trigger event; and in response to having detected the trigger event, copy the information related to the performance of the processor respectively in the plurality of first registers into the second register.

Hardware support for performance analysis

Systems, apparatuses, and methods for system and application debugging are described herein. A tested platform may include a debug event monitor in a boundary scan interface that detects a debug event in a process and determines a characteristic associated with the debug event. The debug event monitor may trigger an application debug event or a boundary scan debug event based at least in part on the determined characteristic. Other embodiments may be described and claimed.

System and application debugging

Embodiments of a method and system for compiling code, such as program-generated code, are disclosed herein. The method and system efficiently encode combined range and stride checks. For example, the method and system are operable to encode combined range and stride checks as they occur in a translation of switch statements. The method and system can generate code to perform the range and stride check, and to branch to the case body, if the range and stride checks are successful. The various embodiments may operate to provide an efficient code transformation, better code density, and processing performance. Other embodiments are described and claimed.

Method and system for efficient range and stride checking

A system for performing code optimization is described which includes an optimizing analyzer within a compiler to generate a first optimizing transformation and a second optimizing transformation and their satisfying conditions for a compiled code. An optimization transformation module is placed within a linker to determine which of the first and second optimizing transformations should be selected when the compiled code is linked with other compiled codes, and to execute the selected one of the first and second optimizing transformations at link-time. A method of performing code optimization is also described.
