==Thread Channel Deactivation based on Instruction Cache Misses - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18054380 titled 'Thread Channel Deactivation based on Instruction Cache Misses

==Simplified Explanation==

The abstract describes a patent application related to instruction scheduling in the context of instruction cache misses. The patent involves first-stage scheduler circuitry assigning threads to channels, second-stage scheduler circuitry assigning operations to execution pipelines based on decode, and thread replacement circuitry deactivating threads in response to cache misses.

* First-stage scheduler circuitry assigns threads to channels
* Second-stage scheduler circuitry assigns operations to execution pipelines based on decode
* Thread replacement circuitry deactivates threads in response to instruction cache misses

== Potential Applications ==
The technology could be applied in high-performance computing systems, embedded systems, and other applications where efficient instruction scheduling is crucial.

== Problems Solved ==
The technology addresses the issue of improving performance in systems by efficiently managing instruction scheduling in the presence of instruction cache misses.

== Benefits ==
The benefits of this technology include improved system performance, reduced latency due to cache misses, and optimized resource utilization.

== Potential Commercial Applications ==
Potential commercial applications of this technology include processors for data centers, high-performance computing systems, and embedded devices.

== Possible Prior Art ==
One possible prior art could be techniques for instruction scheduling in processors, but specific implementations for handling instruction cache misses may not have been addressed.

=== What are the specific techniques used for thread replacement in response to cache misses? ===
The specific techniques for thread replacement in response to cache misses involve deactivating the thread from the channel to optimize resource allocation and improve system performance.

=== How does the second-stage scheduler circuitry determine the assignment of operations to execution pipelines based on decode? ===
The second-stage scheduler circuitry determines the assignment of operations to execution pipelines based on the decode of an operation for a given channel, ensuring efficient utilization of resources and improving overall system performance.


==Original Abstract Submitted==

Techniques are disclosed relating to instruction scheduling in the context of instruction cache misses. In some embodiments, first-stage scheduler circuitry is configured to assign threads to channels and second-stage scheduler circuitry is configured to assign an operation from a given channel to a given execution pipeline based on decode of an operation for that channel. In some embodiments, thread replacement circuitry is configured to, in response to an instruction cache miss for an operation of a first thread assigned to a first channel, deactivate the first thread from the first channel.
