Connecting coprocessors
Connecting a single coprocessor
A coprocessor in an ARM7TDMI processor system must have 32-bit connections to:
•
•
•
The coprocessor can optionally have connections to:
•
•
This section describes:
•
•
An example of how to connect:
•
•
the instruction stream from memory
data written by the core, MCR
data read by the core, MRC.
data written from memory, LDC
data read to memory, STC.
