Patent number: 12174727Abstract: A new approach is proposed to support correlating high-level code with low-level instructions of an application running on a hardware. A compiler that compiles a high-level function in the high-level code of the application into a set of low-level instructions to be executed on the hardware is configured to utilize one or more reserved fields of the set of low-level instructions to incorporate one or more IDs and an actionable item. The IDs are mapped to the high-level function, wherein such mapping is programmable by the compiler. Based on the mapped IDs and the actionable item incorporated in the set of the low-level instructions, the runtime performance of the application on the hardware can be monitored and profiled and issues related to the high-level code of the application can be identified for debugging purposes.Type: GrantFiled: July 30, 2021Date of Patent: December 24, 2024Assignee: Marvell Asia Pte LtdInventors: Ulf Hanebutte, Harri Hakkarainen, Senad Durakovic, Chien-Chun Chou
