Title: Multiple asynchronous request handling
Inventor: BEAN BRADFORD M
IPC: G06F9/52
Filed: 1991-11-29
Abstract: ABSTRACT OF THE DISCLOSURE       Plural requests for storage accessing are processed in plural  stages  of  a  storage-request  pipeline.   Pipeline processing is not interrupted when one or more requests must wait for a resource to  start its processing,  or when a pipeline stage must process for a long period in relation to the  time  allocated  for  a  processing  operation  in  the pipeline.  Waiting is done in a wait path connected to a particular processing stage in the pipeline.  A request is shunted from the pipeline into a wait path when processing the request in the pipeline would delay pipeline processing. When the wait has ended,  a request re-enters the pipeline from  its  wait  path.   The  pipeline  is  provided  in  a multiprocessor (MP) in which storage requests are provided asynchronously  to  a  tightly  coupled  system  storage  and usually may be handled and processed asynchronously by the pipeline.  The  pipeline  output  may  direct  the  processed requests to a shared intermediate cache or to the system main storage.
