The ARM7TDMI-S processor is a member of the 32-bit ARM family of general-purpose 32-bit
microprocessors that offers high performance with very low-power consumption
A three stage instruction pipeline (fetch, decode, execute) increases the speed of the flow of
instructions to the processor
Data access can be 8-bit bytes, 16-bit half words, or 32-bit words. Words must be aligned to 4-byte
boundaries. Half words must be aligned to 2-byte boundaries
The ARM7TDMI-S processor supports two instruction sets, the 32-bit ARM instruction set and the
16-bit Thumb instruction set. The Thumb mode incorporates 16-bit instructions for higher code
density while retaining all the benefits of a 32-bit architecture, such as the full 32-bit registers,
32-bit operations, and 32-bit memory transfer. The use of the instruction sets can be intermixed for
maximizing performance while retaining higher code density
