Abstract
A buffer storage control system is provided having a central processing unit having a buffer storage for storing a part of the content of a main storage, wherein, when a block transfer from the main storage to the buffer storage is carried out, data to be processed is transferred directly to an arithmetic unit or an instruction processing unit via a by-pass operation. The transferred data is then written into the buffer storage and only the portion written in a block can be read, even if not all of the data of one block is written into the buffer storage. During the period from the end of the by-pass operation to the end of the write operation into the buffer storage, with respect to data related to the by-pass operation and data transferred from the main storage, subsequent to the data related to the by-pass operation, the access to the buffer storage based upon a subsequent request for access is inhibited.
