- In computer science, a single address space operating system (or SASOS) is an operating system that provides only one globally shared address space for all processes. In a single address space operating system, numerically identical (virtual memory) logical addresses in different processes all refer to exactly the same byte of data. Single address-space operating systems offer certain advantages. In a traditional OS with private per-process address space, memory protection is based on address space boundaries ("address space isolation"). Single address-space operating systems use a different approach for memory protection that is just as strong. One advantage is that the same virtual-to-physical map page table can be used with every process (and in some SASOS, the kernel as well). This makes context switches on a SASOS faster than on operating systems that must change the page table and flush the TLB caches on every context switch. SASOS projects include the following:
* Amiga family – AmigaOS, AROS and MorphOS
* Angel
* BareMetal
* Br1X
* Genera by Symbolics
* IBM i (formerly called OS/400)
* Iguana at NICTA, Australia
* JX a research Java OS
* IncludeOS
* Mungi at NICTA, Australia
* Nemesis
* Opal
* OS-9
* Phantom OS
* Scout
* Singularity
* Sombrero
* TempleOS
* Theseus OS
* Torsion
* VxWorks
* Zephyr (en)
