Hello, on the homepage of ARM stands that the ARM7TDMI has an interface for a COprocessor. Is it possible to attach to the STR7 mathematical CO a processor?

Are there are any restrictions, which coprocessor I can use. And wheredo i get such Co-Processors?

Hi hugo123,

I think that ARM7TDMI core built in STR7 is isolated from the extern environnement (the microcontroller package), so I think that there are no external interface to a specific co-processor. However, if there are any co-processor which able to communicate with EMI (External Memory Interface), I think it is possible in this case to interface it with STR710 EMI interface.
