11. ARM7TDMI Processor Overview

11.1

Overview

The ARM7TDMI core executes both the 32-bit ARM® and 16-bit Thumb® instruction sets, allowing the user to trade

off between high performance and high code density.The ARM7TDMI processor implements Von Neuman archi-

tecture, using a three-stage pipeline consisting of Fetch, Decode, and Execute stages.

The main features of the ARM7TDMI processor are:

• ARM7TDMI Based on ARMv4T Architecture

• Two Instruction Sets

– ARM® High-performance 32-bit Instruction Set

– Thumb® High Code Density 16-bit Instruction Set

• Three-Stage Pipeline Architecture

– Instruction Fetch (F)

– Instruction Decode (D)

– Execute (E)
