RTEMS CPU Architecture Supplement
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.
