IORegister IODeviceTree:/memory - convert DATA Entry

Hi,

I'm trying to parse out each DIMM size of the machines available ram,  I know this can be found in the IORegistry at:

IORegister IODeviceTree:/memory

Key: reg


Now my problem is I don't know how to read this data correctly,  like how do I know what format the DATA is in?

All i know is this:

00000000000000800000000000000080, should be broken up into 0000000000000080 and 0000000000000080, for each DIMM.

and 

0000000000000080 = 2gig
0100000000000000 = 4gig

but how can I correctly convert (0100000000000000 or 0000000000000080) into a readable number?


Thanks,
Coin
