摘要：A buffer-storage control system used in a pipeline data processor comprises amemory system having a two-level hierarchical structure composed of a main storage (3,Figure 1) and a buffer storage (8). The buffer storage (8) has a tag portion (21) and a dataportion (22), each portion being composed of a plurality of ways. In the buffer-storage
control sytem, the tag portion (21) and the data portion (22) can be independentlyaccessed and the data portion (22) is so constituted for every way that it is possible toselect one of a plurality of address passes and to select an address for a read access andan address for a write access for every way, thereby simultaneously effecting a readoperation and write operation in the same machine cycle and executing the read accessagain only when the read access and the write access are effected for the same way.
