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.
