Virtual memory map
The VAX virtual memory is divided into four sections. Each is one gigabyte (in the context of addressing, 230 bytes) in size:
| Section | Address Range |
|---|---|
| P0 | 0x00000000 - 0x3fffffff
|
| P1 | 0x40000000 - 0x7fffffff
|
| S0 | 0x80000000 - 0xbfffffff
|
| S1 | 0xc0000000 - 0xffffffff
|
For VMS, P0 was used for user process space, P1 for process stack, S0 for the operating system, and S1 was reserved.
