6 Φεβ 2015 · It can only point to 1 byte at a time, out of that total of 2^64 unique bytes. To process all those 2^64 bytes, you would need 2^64 strokes (not counting all the overhead "strokes" the CPU needs to do).
25 Ιουλ 2010 · A 64-bit machine should be able to address up to 2 64 addressable units (in architectures designed over the last few decades, addressable units are invariably bytes, a.k.a. octets). If you define a "gigabyte" as 2 30 addressable units, then yes, 2 34 gigabytes would be another way to express the same count.
28 Μαρ 2010 · In a 64bit processor, the processor can (in theory) use 64 bits to address memory, or 2^64 bytes of addressable memory. I believe that amounts to 16 Exo Bytes, which is a huge amount that is almost to the point of counting the amount of molecules in your machine.
On google they just explain that a 64-bit address can represent $2^{64}$ different values and thus it equates to the processor being able to process $2^{64}$ values (or memory locations) at a single time, though I am interested in as much detail as possible regarding how exactly that looks like.
3 Αυγ 2022 · The electronics have unused values in counting through bits and bytes. If memory fetches are 32 bits, then 40-bit pointers always require two fetches; if memory fetches are 40 bits, then some of your 16-bit and 32-bit fetches require two fetch operations, and some of your 64-bit fetches need three.
5 Οκτ 2014 · A key characteristic is the memory address itself will be 32bits or 64bits, and hence could access upto \$2^{32}\text{ and }2^{64}\$ units of memory, bytes. A simple view is a 32bit bit processor typically operates on 32bits of data, and a 64bit CPU acts on 64 bit data.
3 Μαρ 2021 · Ever wondered what they really are - bits, bytes and binary? Similar in sound, quite different in what they mean, this article introduces you to computers at their core: we take it down to the physical level and more.
