Memory Map Unit, Interdata 7/16 HSALU: description and instructions

The Memory Map Unit (MMU) provides the capability for an Interdata 7/16 computer with High Speed Arithmetic Logic Unit (HSALU) to operate with up to 256K bytes of memory (1K = 1024). Memory addresses, consisting of 16 bits, are mapped into 18 bits whenever a memory cycle occurs. Mapping occurs by 1K pages; selectable low-address areas are not mapped. 4 figures.
