About the ARM7TDMI core
The instruction pipeline
The ARM7TDMI core is a member of the ARM family of general-purpose 32-bit
microprocessors. The ARM family offers high performance for very low power
consumption, and small size.
The ARM architecture is based on Reduced Instruction Set Computer (RISC)
principles. The RISC instruction set, and related decode mechanism are much simpler
than those of Complex Instruction Set Computer (CISC) designs. This simplicity gives:

The ARM7TDMI core uses a pipeline to increase the speed of the flow of instructions
to the processor. This allows several operations to take place simultaneously, and the
processing and memory systems to operate continuously.
A three-stage pipeline is used, so instructions are executed in three stages:
