INPUT/OUTPUT (I/O) STORE PROTOCOL FOR PIPELINING COHERENT OPERATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17962829 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 I/O requestor. The I/O requestor issues snoop requests for I/O store operations, receives ownership coherence responses, and then issues execute coherence responses to command the coherence manager to initiate updates to storage locations.

• The system fabric includes a coherence manager and an I/O requestor.
• The I/O requestor issues snoop requests for I/O store operations.
• Ownership coherence responses are received for each I/O store operation.
• Execute coherence responses are issued to command the coherence manager to initiate updates to storage locations.

Potential Commercial Applications

Potential commercial applications of this technology include server systems, network appliances, storage devices, and any other computing systems where data coherence and efficient memory management are essential for optimal performance.

Possible Prior Art

One possible prior art for this technology could be cache coherence protocols used in multiprocessor systems to maintain consistency among caches and main memory.

How does this technology impact energy efficiency in data processing systems?

This article does not address the potential energy efficiency implications of the described data processing system. Implementing coherence management techniques may have an impact on energy consumption, but further research is needed to determine the extent of this impact.

What are the scalability limitations of this technology in large-scale distributed systems?

The article does not discuss the scalability limitations of the described technology in large-scale distributed systems. Understanding how this system performs and scales in complex distributed environments is crucial for assessing its practical applicability in real-world scenarios.

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.
