  • Paulius M thinks this is interesting:

The EDB gradually increased in size, from 8- to 16- to 32- to 64-bits wide. The address bus similarly jumped, going from 20- to 24- to 32-bits wide (where it stayed for a decade).


Has the address bus reached 64-bits wide? What is the relation between EDB evolution and address bus evolution? I mean, does the EDB change to 16-bits definitely results to address bus change to 24-bits, and the EDB change to 32-bit results to address bus changed to 32-bit and so on? If these changes (EDB and address bus) is related then where is the cause of this relation?
