摘要
The present disclosure generally relates to prefetching data from one or more CPUs prior to the data being requested by a host device. The prefetched data is prefetched from memory and stored in cache. If a host device requests data that is not already in cache, then a determination is made regarding whether the data is scheduled to be written into cache. If the data is not in cache and is not scheduled to be written into cache, then the data is retrieved from memory and delivered to the host device. If the data is scheduled to be written into cache, or is currently being written into cache, then the request to retrieve the data is delayed or scheduled to retrieve the data once the data is in cache. If the data is already in cache, the data is delivered to the host device.
