Title: Data processing systems
IPC: G06F12/10
Filed: 1973-07-30
Abstract: 1438039 Virtual memory systems INTERNATIONAL BUSINESS MACHINES CORP 30 July 1973 [17 Oct 1972] 36123/73 Heading G4A In a virtual memory system employing a look-aside table DLAT containing currently available virtual to real address translations, each entry of DLAT is provided with an indication ID of the tables which were used to obtain the corresponding translation. Control registers 51, Fig. 6A, store a segment table origin (STO) address and indications of page and segment sizes. An STO stack (STOK) 55 stores six STO addresses together with page and segment sizes and is loaded from control registers 51. Normally a particular word in STOK is accessed by a pointer 59 held stationary by a latch 71 which is set when the data in control registers 51 and the accessed STOK word agree. When a change in STO or page or segment size occurs, latch 71 releases pointer 59 which is then sequenced by a counter 63 until the corresponding STO, page and segment sizes are found. If no corresponding data is found, FIFO supplies the address of the oldest word in STOK, and this address is loaded with data from registers 51. FIFO is then updated to indicate the address of the oldest remaining word. Generator 49 provides the ID code, representing the address of the word currently accessed in STOK and supplies it to DLATto be stored with the appropriate virtual address and its translation. When a STOK word is changed as described above, the corresponding entries in DLAT are invalidated by changing their ID code to 000. DLAT is addressed by hash-coding (e.g. exclusive ORing) the ID bits from generator 49 and the segment and page address bits of a virtual address supplied by the CPU. The use of the DLAT and buffer directory 56, Fig. 6B, to determine whether DLAT has been properly addressed, whether the data requested is in the high speed buffer and whether a virtual-toreal address translation is required, is as described in Specification 1,342,459. The use of address prefixing and storage protection keys in the DLAT entries is also briefly described.
