Abstract: An apparatus and method for efficiently performing error reporting of an integrated circuit. In various implementations, a computing system includes multiple functional blocks used to process one or more applications. The functional blocks are components of an integrated circuit such as a processing circuit, a processor core, a particular level of a cache memory hierarchy, a memory controller that interfaces with one or more memory devices, an input/output controller that interfaces with a peripheral device, a network interface, and so on. A combination of sensors, hardware performance counters, and control circuits monitor environmental conditions of the multiple functional blocks. When an error occurs or a time interval has elapsed, an error reporting circuit retrieves and stores parameters characterizing the environmental conditions. This information can be used at a later time for error debugging, searching for a minimum power supply voltage, and other transient state data processing.

Abstract: A first node obtains a corresponding physical address based on a first virtual address in a first request. The first request may be sent by an application in the first node, and is used to request to read data of a second node or request to write data to the second node. Then, the first node sends a second request corresponding to the first request to the second node based on a first mapping relationship. Because the bus address indicates a virtual address corresponding to an instance of the second node, when the virtual address may be accessed by the first node based on the first request, the virtual address may be accessed by the second node, or may be accessed by another node based on a request, to implement address sharing in data access.
