Register View of a Simple P aka “Von Neumann” or “Princeton” architecture

Register View of a Simple P with Isolated I/O space Most microprocessors do NOT have isolated I/O. The Intel x86 microprocessors do.

Register View of a Simple P with Separate Code and Data Memories aka “Harvard” architecture

Endian-ness Byte Ordering for Little Endian vs. Big Endian Big Endian Most Significant Byte (MSB) Least Significant Byte (LSB) Example: int x = 0x1234; Big-endian 12 34 Motorola, SPARC (big end in first byte) Little-endian 34 12 Intel (little end in first byte) The MIPS processor and compilers support both the Big Endian and Little Endian byte-ordering conventions. The names Big Endian and Little Endian are used because of the apt analogy to the bloody feud in the classic children's book Gulliver's Travels (quod vide). The feud was between the two mythical islands, Lilliput and Blefescu, over the correct end (big or little) at which to crack an egg. In our case, the issue has to do with the "end" (most significant or least significant) of a multiple-byte data type. With Big Endian ordering, the address of a multiple-byte data type is of its most significant byte (its "big end"), whereas with Little Endian ordering, the address is of its least significant byte (its "little end"). This is shown in Figure A.14. For structures declared in a high-level language, the order of bytes in memory will differ depending on the byte ordering and the particular data type, as shown for a C structure in Figure A.15. Most UNIXes (for example, all System V) and the Internet are Big Endian. Motorola 680x0 microprocessors (and therefore Macintoshes), Hewlett-Packard PA-RISC, and Sun SuperSPARC processors are Big Endian. The Silicon Graphics MIPS and IBM/Motorola PowerPC processors are both Little and Big Endian (bi-endian). The ARM7 can be implemented as bi-endian, but traditionally has been implemented as little-endian. Memory Address +0 +1 +2 +3 Big Endian Byte 3 Byte 2 Byte 1 Byte 0 MSB in the lowest (first) memory address Little Endian LSB in the lowest (first) memory address
