11. ARM7TDMI Processor Overview
11.1
6120I–ATARM–06-Apr-11
Overview
The ARM7TDMI core executes both the 32-bit ARM
ing 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
• Three-Stage Pipeline Architecture
– ARM
– Thumb
– Instruction Fetch (F)
– Instruction Decode (D)
– Execute (E)
