Connecting coprocessors
Connecting a single coprocessor
A coprocessor in an ARM9E-S system needs to have 32-bit connections to:
•
•
•
An example of how to connect a coprocessor into an ARM9E-S system is shown in
Figure 6-11.
The logic for Figure 6-11 is as follows:
on RISING CLK
asel = not (DnMREQ and DSEQ) and (not DnRW)
bsel = (not DnMREQ) and (not PASS)
csel = DnMREQ and DSEQ
data from memory (instruction stream and
write data from the ARM9E-S (
