Nvidia patents software command to clear old data from processor memory
Nvidia describes a method where a software command tells a computer's processor to erase outdated data stored in a temporary memory area, known as a cache. This ensures that when the processor needs to use that data again, it fetches the most current version instead of using an old copy.
In the filing’s own words
Apparatuses, systems, and techniques to cause information to be invalidated in a second cache location after information is stored in a first cache location. In at least one embodiment, one or more circuits are to perform an application programming interface (API) to cause information to be invalidated in a second cache location after information is stored in a first cache location.
What exactly they claim (claim 1)
1. One or more processors, comprising circuitry to, in response to an application programming interface (API) call: responsive to determining that first cache information associated with a first processor is stored in a first cache location: invalidate second cache information associated with a second processor in a second cache location identified by a second identifier after the first cache information is stored in the first cache location; and prevent execution of subsequent instructions that access an address corresponding to the second cache location identified by the second identifier.
