1 dynamic address translation https://store.theartofservice.com/the-dynamic-address-translation-toolkit.html

2 Hypervisor - Mainframe origins 1 CP-40 ran on a S/360-40 that was modified at the IBM Cambridge Scientific Center to support Dynamic Address Translation, a key feature that allowed virtualization https://store.theartofservice.com/the-dynamic-address-translation-toolkit.html

3 Memory management unit - IBM System/370 and successors 1 It was initially known as a dynamic address translation (DAT) box https://store.theartofservice.com/the-dynamic-address-translation-toolkit.html

4 System 360 - Models 1 There was a System/370 version of the 195, but it did not include Dynamic Address Translation. https://store.theartofservice.com/the-dynamic-address-translation-toolkit.html

5 System 360 - Models 1 The IBM System/360 Model 67|Model 67, announced in August 1965, was the first production IBM system to offer dynamic address translation hardware to support time-sharing https://store.theartofservice.com/the-dynamic-address-translation-toolkit.html

6 Host machine - Mainframe origins 1 CP-40 ran on a System/360|S/360-40 that was modified at the IBM Cambridge Scientific Center to support Dynamic Address Translation, a key feature that allowed virtualization https://store.theartofservice.com/the-dynamic-address-translation-toolkit.html

7 Virtual memory - History 1 Dynamic address translation required expensive and difficult to build specialized hardware; initial implementations slowed down access to memory slightly https://store.theartofservice.com/the-dynamic-address-translation-toolkit.html

8 History of IBM mainframe operating systems - Virtual memory 1 *'Dynamic Address Translation hardware' (sometimes called a DAT box in early systems because of its separate enclosure) is integrated into the CPU itself and participates in every memory reference https://store.theartofservice.com/the-dynamic-address-translation-toolkit.html

9 CP-40 - Hardware platform 1 * The DAT Box (Dynamic Address Translation), announced as an addition to the S/370 series in 1972 https://store.theartofservice.com/the-dynamic-address-translation-toolkit.html

10 CP-40 - Hardware platform 1 about the CP-40 virtual memory hardware, and states that it was unique in that it included a parallel-search register bank to speed dynamic address translation https://store.theartofservice.com/the-dynamic-address-translation-toolkit.html

11 Michigan Terminal System - Origins 1 1966 The paper outlined a virtual memory architecture using dynamic address translation (DAT) that could be used to implement time-sharing. https://store.theartofservice.com/the-dynamic-address-translation-toolkit.html

12 Michigan Terminal System - Origins 1 After a year of negotiations and design studies, IBM agreed to make a one-of-a- kind version of its S/360-65 mainframe computer with dynamic address translation (DAT) features that would support virtual memory and accommodate UM's desire to support time-sharing https://store.theartofservice.com/the-dynamic-address-translation-toolkit.html

14 History of CP/CMS - Historical notes 1 * 'Virtual memory and timesharing:' In June [1964]...[MIT was] adamant that hardware-aided dynamic address translation (DAT) was essential for time- sharing, a still-experimental mode of operation whereby users at several consoles could share the facilities of a computer... https://store.theartofservice.com/the-dynamic-address-translation-toolkit.html

15 History of CP/CMS - Historical notes 1 ** Unifying the architecture and control programs of business and scientific computers both large and small (championed by Brooks/Amdahl; this group rejected dynamic address translation, fearing unevaluated techniques or technologies as the basis of an entire product line), versus https://store.theartofservice.com/the-dynamic-address-translation-toolkit.html

16 System/370 - Architecture details 1 * A Dynamic Address Translation mechanism that can be used to implement a virtual memory system https://store.theartofservice.com/the-dynamic-address-translation-toolkit.html

17 IBM System/360-67 - Origins 1 After a year of negotiations and design studies, IBM agreed to make a one-of-a- kind version of its S/360-65 mainframe computer for the University of Michigan. The S/360-65M would include dynamic address translation (DAT) features that would support virtual memory and allow support for time-sharing. Initially IBM decided not to supply a time-sharing operating system for the new machine. https://store.theartofservice.com/the-dynamic-address-translation-toolkit.html

18 System/360 - Models 1 There was a System/370 version of the 195, but it did not include Dynamic Address Translation. https://store.theartofservice.com/the-dynamic-address-translation-toolkit.html

19 APL (programming language) - History 1 APL gained its foothold on mainframe timesharing systems from the late 1960s through the early 1980s, in part because it would run on lower-specification systems that were not equipped with Dynamic Address Translation hardware https://store.theartofservice.com/the-dynamic-address-translation-toolkit.html

20 Amdahl Corporation - Company origins 1 launched its first product, the Amdahl 470/6, in 1975, competing directly against IBM's high-end machines in the then- current System/370 family, but with IBM's announcement of Dynamic Address Translation (DAT), Amdahl announced the 470V/6 and dropped the 470/6 https://store.theartofservice.com/the-dynamic-address-translation-toolkit.html

21 ESi-RISC - Architecture 1 * Optional Memory management unit|MMU supporting both memory protection and dynamic address translation. https://store.theartofservice.com/the-dynamic-address-translation-toolkit.html
