SYSTEM FOR LINK MANAGEMENT BETWEEN MULTIPLE COMMUNICATION CHIPS

Embodiments relate to an integrated circuit of an electronic device that coordinates activities with another integrated circuit of the electronic device. The integrated circuit includes an interface circuit and a processor circuit. The interface circuit communicates over a multi-drop bus connected to multiple electronic components. The processor circuit receives an authorization request from the integrated circuit via the interface circuit and the multi-drop bus. The received authorization request relates to authorization to perform an activity on the other integrated circuit. In response to receiving the authorization request, the processor circuit determines whether the other integrated circuit is authorized to execute the activity. In response to determining that the other integrated circuit is authorized to execute the activity, the processor circuit sends, to the other integrated circuit over a configurable direct connection, an authorization signal authorizing the other integrated circuit to execute the activity.

APPROACH FOR REDUCING SIDE EFFECTS OF COMPUTATION OFFLOAD TO MEMORY
20230004491 · 2023-01-05 ·

A technical solution to the technical problem of how to reduce the undesirable side effects of offloading computations to memory uses read hints to preload results of memory-side processing into a processor-side cache. A cache controller, in response to identifying a read hint in a memory-side processing instruction, causes results of the memory-side processing to be preloaded into a processor-side cache. Implementations include, without limitation, enabling or disabling the preloading based upon cache thrashing levels, preloading results, or portions of results, of memory-side processing to particular destination caches, preloading results based upon priority and/or degree of confidence, and/or during periods of low data bus and/or command bus utilization, last stores considerations, and enforcing an ordering constraint to ensure that preloading occurs after memory-side processing results are complete.
