US 11,113,194 B2 · Producer-to-consumer active direct cache transfers

Abstract

The embodiments herein creates DCT mechanisms that initiate a DCT at the time the updated data is being evicted from the producer cache. These DCT mechanisms are applied when the producer is replacing the updated contents in its cache because the producer has either moved on to working on a different data set (e.g., a different task) or moved on to working on a different function, or when the producer-consumer task manager (e.g., a management unit) enforces software coherency by sending Cache Maintenance Operations (CMO). One advantage of the DCT mechanism is that because the direct cache transfer takes place at the time the updated data is being evicted, by the time the consumer begins its task, the updated contents have already been placed in its own cache or another cache within the cache hierarchy.

Dependent claims

A computing system, comprising:

a producer comprising a first processing element configured to generate processed data;
a producer cache configured to store the processed data generated by the producer;
a consumer comprising a second processing element configured to receive and process the processed data generated by the producer;
and
a consumer cache configured to store the processed data generated by the consumer,
wherein the producer is configured to, in response to receiving a stash cache maintenance operation (stash-CMO), perform a direct cache transfer (DCT) to transfer the processed data from the producer cache to the consumer cache.
