ARM DDI 0180A
Instruction set extension spaces
All ARM processors implement the undefined instruction space as one of the entry
mechanisms for the Undefined Instruction Exception. That is, ARM instructions with
opcode[27:25] = 0b011 and opcode[4] = 1 are UNDEFINED on all ARM processors
including the ARM9TDMI and ARM7TDMI.
ARM Architecture v4 and v4T also introduced a number of instruction set extension
spaces to the ARM instruction set. These are:
•
•
•
•
Instructions in these spaces are UNDEFINED (they cause an Undefined Instruction
Exception). The ARM9TDMI fully implements all the instruction set extension spaces
defined in ARM Architecture v4T as UNDEFINED instructions, allowing emulation of
future instruction set additions.
arithmetic instruction extension space
control instruction extension space
coprocessor instruction extension space
load/store instruction extension space.
