Rabbit Memory Management In a Nutshell
Introduction
The Rabbit CPU has a Memory Management Unit (MMU) that controls how logical mem-
ory addresses map into physical addresses, and a Memory Interface Unit that controls how
physical addresses map into actual hardware.
The Dynamic C compiler and libraries generally handle memory mapping details so that
most Dynamic C users don’t have to concern themselves with it, but some advanced appli-

For further details on the Rabbit memory management, see the Rabbit 2000 Microproces-
sor User’s Manual
