APPARATUSES AND METHODS FOR PROVIDING DATA CONSISTENCY MESSAGING FOR SHARED MEMORY SYSTEMS

摘要

Apparatuses and methods for providing data consistency messaging for shared memory systems are disclosed herein. An example apparatus may include a producer processor unit configured to provide a memory access packet and a first notification packet. The first notification packet may include identification of a consumer processor unit. The example apparatus may further include a shared resource configured to receive the memory access packet and the notification packet. Responsive to reception of the memory access packet, the shared resource may be configured to perform a memory access operation. Responsive to reception of the notification packet, the shared resource may be further configured to route a first notification packet to the consumer processor unit. The second notification packet may include information indicating the shared resource is available.

1. An apparatus comprising:
a shared memory configured to receive a first packet and a second packet from a first processor unit of a plurality of processor units, responsive to reception of the first packet, the shared memory configured to perform a memory access operation at an address specified in the first packet, responsive to reception of the second packet, the shared memory further configured to route a third packet to a second processor unit of the plurality of processor units based on information included in the second packet, wherein the third packet includes information that indicates that the address of the shared memory is available to be accessed by the second processor unit.
