ARM7TDMI Processor Overview
Overview
1790A–ATARM–11/03
The ARM7TDMI core executes both the 32-bit ARM
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.
