GPMC interface of AM3874 to custom logic

Poh Boon Teo

Other Parts Discussed in Thread: AM3874

Hi,

The GPMC interface of the AM3874 is connected to a DSP and Nand flash in our custom board.

The asynchronous, non multiplexed mode seems to allow only access up to address 10. The other way is to go asynchronous, multiplexed mode but I do not wish to add additional components due to space constraint.

My question is whether can I use the GPMC bus to communicate to the custom logic (DSP) in non-multiplexed, synchronous mode which allows me to access up to address 26?

Our DSP happens to have a Motorola type interface which cannot be connected gluelessly to the GPMC bus on the AM3874, is there any document talking about this where I can refer to?

Please advise.

Thanks and regards,

pb
