ABSTRACT:
A storage control apparatus of a computer system having a plurality of transfer pipelines issuing access requests to a plurality of memory banks of a storage device. Each memory bank is independently accessible in response to an access instruction from a vector processing device. Each of the transfer pipelines includes a plurality of access request control devices to which the access instruction from the vector processing device is allocated in association with elements of a vector. The access request control devices simultaneously issue in response to an access instruction a plurality of access requests. Each transfer pipeline also includes a priority decision device which detects whether or not the access requests forecasted to be issued from the plural access request control devices contend with the access requests issued from the plural access request control devices of another transfer pipeline. In a case where it is detected that a contention takes place, processing of the access requests of another transfer pipeline effecting the succeeding access instruction is set to a wait state such that the access requests of the pertinent transfer pipeline effecting the preceding access instruction are preferentially processed.
