Load adaptive data recovery pipeline

摘要

A load adaptive pipeline system includes a data recovery pipeline configured to transfer data between a memory and a host. The pipeline includes a plurality of resources, one or more of the plurality of resources in the pipeline have multiple resource components available for allocation. The system includes a pipeline controller configured to assess at least one parameter affecting data transfer through the pipeline. The pipeline controller is configure to allocate resource components to the one or more resources in the pipeline in response to assessment of the at least one data transfer parameter.

1. A system comprising:
a memory; a data recovery pipeline configured to transfer data between the memory and a host processor, the data associated with a root job, the pipeline comprising a plurality of resources, one or more of the plurality of resources in the pipeline having multiple resource components available for allocation; and a pipeline controller configured to:
create a sub-job for each subset of one or more code words in the data associated with the root job;estimate a data transfer time for each sub-job;determine a pipeline stage transfer time for each pipeline stage;determine a total estimated latency for the sub-job based on the estimated data transfer time and a sum of the pipeline stage transfer times;assess at least one parameter affecting data transfer through the pipeline; andallocate resource components to the one or more resources in the pipeline in response to assessment of the at least one data transfer parameter and the total estimated latency for the sub-job.
