>From the ARM ARM (Architecture Ref. Manual):
"Architecture "Version 4" added halfword loads and stores, sign-extending byte and
half-word load, a new privileged mode and defines several new undefined instructions"
The ARM7, ARM710, StrongARM1 (eg SA-110) are all Version 4 architectures, as is ARM9.
In fact, Most ARM7 are ARM7T (they include the Thumb instruction set) which is
architecture 4T.
