RTEMS supports a flat memory -model which ranges contiguously over the processor's allowable -address space. RTEMS does not support segmentation or virtual -memory of any kind. The appropriate memory model for RTEMS -provided by the targeted processor and related characteristics -of that model are described in this chapter. - -@section Flat Memory Model - -The XXX family supports a flat 32-bit address -space with addresses ranging from 0x00000000 to 0xFFFFFFFF (4 -gigabytes). Each address is represented by a 32-bit value and -is byte addressable. The address may be used to reference a -single byte, word (2-bytes), or long word (4 bytes). Memory -accesses within this address space are performed in big endian -fashion by the processors in this family. - -Some of the XXX family members such as the -XXX, XXX, and XXX support virtual memory and -segmentation. The XXX requires external hardware support -such as the XXX Paged Memory Management Unit coprocessor -which is typically used to perform address translations for -these systems. RTEMS does not support virtual memory or -segmentation on any of the XXX family members. - |
