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 architecture,
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)
