Fence Enforcement Techniques based on Stall Characteristics - A simplified explanation of the abstract
This abstract first appeared for US patent application 18054401 titled 'Fence Enforcement Techniques based on Stall Characteristics
Simplified Explanation
The patent application describes techniques for managing channel stalls or deactivations based on the latency of prior operations in a processor system.
- The processor includes multiple channel pipelines and execution pipelines shared by the channel pipelines.
- First scheduler circuitry assigns threads to channels, while second scheduler circuitry assigns operations to execution pipelines based on operation decode.
- Dependency circuitry determines whether to stall a new operation or deactivate a thread based on status information from prior operations.
Potential Applications
This technology could be applied in high-performance computing systems, data centers, and other complex processing environments where efficient management of operations is crucial.
Problems Solved
This technology addresses the issue of optimizing processor performance by managing channel stalls and deactivations based on the latency of prior operations, reducing bottlenecks and improving overall efficiency.
Benefits
The benefits of this technology include improved processor efficiency, reduced latency, better resource utilization, and enhanced overall system performance.
Potential Commercial Applications
Potential commercial applications of this technology include server systems, supercomputers, cloud computing infrastructure, and any other computing environment where high-performance processing is required.
Possible Prior Art
One possible prior art in this field could be techniques for managing pipeline stalls in processors, but the specific approach of using latency of prior operations to determine channel stalls or deactivations may be novel.
What are the specific types of operations performed by the execution pipelines in the processor system described in the patent application?
The specific types of operations performed by the execution pipelines in the processor system are different types of operations provided by the channel pipelines.
How does the dependency circuitry determine whether to stall a new operation or deactivate a thread in the processor system?
The dependency circuitry determines whether to stall a new operation or deactivate a thread based on status information for the prior operation from the execution pipelines.
Original Abstract Submitted
Techniques are disclosed relating to channel stalls or deactivations based on the latency of prior operations. In some embodiments, a processor includes a plurality of channel pipelines for a plurality of channels and a plurality of execution pipelines shared by the channel pipelines and configured to perform different types of operations provided by the channel pipelines. First scheduler circuitry may assign threads to channels and second scheduler circuitry may assign an operation from a given channel to a given execution pipeline based on decode of an operation for that channel. Dependency circuitry may, for a first operation that depends on a prior operation that uses one of the execution pipelines, determine, based on status information for the prior operation from the one of the execution pipelines, whether to stall the first operation or to deactivate a thread that includes the first operation from its assigned channel.
