RTEMS CPU Architecture Supplement
The SuperH 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 SuperH family members support virtual memory and segmentation. RTEMS does not support virtual memory or segmentation on any of the SuperH family members. It is the responsibility of the BSP to initialize the mapping for a flat memory model.
