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

Potential Applications

The technology described in the patent application could be applied in various fields such as:

• High-performance computing
• Data centers
• Cloud computing

Problems Solved

The technology addresses several issues, including:

• Ensuring data coherence in a multi-processor system

Possible Prior Art

One possible prior art related to this technology is the use of cache coherence protocols in multi-processor systems to maintain data consistency.

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

The abstract does not provide information on the energy efficiency implications of the described technology. Further research is needed to understand its impact on energy consumption.

What are the scalability limitations of this data processing system?

The scalability of the system in terms of the number of processors and memory addresses it can handle simultaneously is not addressed in the abstract. Additional investigation is required to determine the scalability limitations of the technology.

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.
