Non-intrusive hardware profiling

Abstract:

Systems and methods for non-intrusive hardware profiling are provided. In some cases integrated circuit devices can be manufactured without native support for performance measurement and/or debugging capabilities, thereby limiting visibility into the integrated circuit device. Understanding the timing of operations can help to determine whether the hardware of the device is operating correctly and, when the device is not operating correctly, provide information that can be used to debug the device. In order to measure execution time of various tasks performed by the integrated circuit device, program instructions may be inserted to generate notifications that provide tracing information, including timestamps, for operations executed by the integrated circuit device.
