This glossary describes some of the terms used in this manual. Where terms can have
several meanings, the meaning presented here is intended.
Is caused by an illegal memory access. Abort can be caused by the external memory
system, an external MMU or the EmbeddedICE Logic.
A procedure shared by many different instructions, for generating values used by the
instructions. For four of the ARM addressing modes, the values generated are memory
addresses (which is the traditional role of an addressing mode). A fifth addressing mode
generates values to be used as operands by data-processing instructions.
The part of a computer that performs all arithmetic computations, such as addition and
multiplication, and all comparison operations.
See Arithmetic Logic Unit.
A processor that is executing ARM (32-bit) instructions is operating in ARM state.
Memory organization where the least significant byte of a word is at a higher address
than the most significant byte.
Register numbers whose physical register is defined by the current processor mode. The
banked registers are registers R8 to R14.
