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 i960CA supports a flat 32-bit address space with -addresses ranging from 0x00000000 to 0xFFFFFFFF (4 gigabytes). -Although the i960CA reserves portions of this address space, -application code and data may be placed in any non-reserved -areas. Each address is represented by a 32-bit value and is -byte addressable. The address may be used to reference a single -byte, half-word (2-bytes), word (4 bytes), double-word (8 -bytes), triple-word (12 bytes) or quad-word (16 bytes). The -i960CA does not support virtual memory or segmentation. - -The i960CA allows the memory space to be partitioned -into sixteen regions which may be configured individually as big -or little endian. RTEMS assumes that the memory regions in -which its code, data, and the RTEMS Workspace reside are -configured as little endian. - - |
