Hi, > 1. The size of the processor's internal address bus (virtual address > space) is what qualifies it as a 32-bit / 64-bit processor. Well, in that sense, isn't Pentium a "36-bit" processor (since it gives the option of PAE to use 64 GB of memory - it must be having atleast 36 address lines)? On this topic and in this thread, we have had following responses to the question on what is called a 32-bit or 64-bit processor: 1) Addressable Physical memory (=sizeof(void*)) 2) Register Size (=instruction size) Are the above two independent of each other? If yes, then how do we deine a processor as 32-bit / 64-bit?
