Multi-stage Thread Scheduling - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240095065 titled 'Multi-stage Thread Scheduling
Simplified Explanation
The patent application describes techniques for multi-stage thread scheduling in processor circuitry, including multiple channel pipelines and execution pipelines shared by the channel pipelines. The first scheduler circuitry assigns threads to channels, while the second scheduler circuitry assigns operations from channels to execution pipelines. Backpressure information from execution pipelines is used to adjust thread priorities, reducing channel conflicts and resource starvation.

Original Abstract Submitted
techniques are disclosed relating to multi-stage thread scheduling. in some embodiments, processor circuitry includes multiple channel pipelines for multiple channels and multiple execution pipelines shared by the channel pipelines and configured to perform different types of operations provided by the channel pipelines. first scheduler circuitry may arbitrate among threads to assign threads to channels. second scheduler circuitry may arbitrate among channels to assign an operation from a given channel to a given execution pipeline. the execution pipelines may provide backpressure information to the first scheduler circuitry based on execution status and the first scheduler circuitry may adjust priority of a thread for assignment to a channel based on the backpressure information. disclosed techniques may reduce channel conflicts and starvation for execution resources.
