INPUT/OUTPUT (I/O) STORE PROTOCOL FOR PIPELINING COHERENT OPERATIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240119000 titled 'INPUT/OUTPUT (I/O) STORE PROTOCOL FOR PIPELINING COHERENT OPERATIONS
Simplified Explanation
The abstract describes a data processing system that includes a coherence manager and an input/output requestor. The requestor issues snoop requests for store operations, receives ownership coherence responses, and commands the coherence manager to initiate updates to storage locations.
- Coherence manager and input/output requestor in data processing system
- Snoop requests issued for store operations
- Ownership coherence responses received
- Coherence manager updates storage locations based on commands from requestor

Original Abstract Submitted
a data processing system includes a system fabric coupling a coherence manager and an input/output (i/o) requestor. the i/o requestor issues a first snoop request of a first i/o store operation and a subsequent second snoop request of a second i/o store operation. each of the first and second snoop requests specifies an update to a respective storage location identified by a coherent memory address. the i/o requestor receives respective ownership coherence responses for each of the first and second i/o store operations. the respective first and second ownership coherence responses indicate the coherence manager has concurrent coherence ownership of the memory address for both the first and second i/o store operations. in response to receipt of each of the ownership coherence responses, the i/o requestor issues respective first and second execute coherence responses to command the coherence manager to initiate updates to the respective storage locations.
