Abstract
A technique includes identifying an address of a head end of a queue and monitoring a coherent interconnect to identify a data transfer that is communicated by a producer, which targets the address. The technique includes storing the data of the data transfer in the queue and selectively storing at least a portion of the data in a head-of-queue cache memory based at least in part on whether the monitoring identifies the address. At least a portion of the data is selectively retrieved from the head-of-queue cache memory instead of from the queue for transmission to a consumer.
