64-bit IA-32, AMD and all that
What is the meaning comilation in 32-bit mode and 64-bit mode? There isn't really compilation in 32-bit mode or 64-bit mode. There are 32-bit compilers and 64-bit compilers. Can 64-bit complier (which will generate 64-bit applications) run on a 32-bit OS? thanks, regards, Naresh Agarwal "Ron Ruble"

32-bit vs 64-bit

64 bit vs. 32 bit memory interfaces for MPC601. (Was: PowerPC)
In the x86-32 world this is already handled using nasty Physical Address Extension (PAE) hacks. The bottom line is Apple needs to develop a 64-bit For most desktop uses, the main benefit of AMD64 will be more registers, and not 64-bit itself. There are some advantages to running 32-bit applications under a

AIX 5L - 64 bit or 32 bit?
AMD has positioned the K7 in anticipation of a migration to 64 bit PC computing and rumour has it that they are technically prepared. AMD is pretty much 64 bit ready? Sorry but this is nonsense. AMD only makes IA-32 (ie x86) based processors. IA-32 is most definitely a 32 bit instruction set architecture.

difference b/w 32-bit vs. 64-bit kernel
Anyway, some of them were describing performance measurements on Alphas with 32-bit and 64-bit code (these two numbers applie to the pointer size). And, predictably, the code with 64-bit pointers was slower. Why? Because you still have the same size of CPU cache, but you can put less data in there.

64 bit vs. 32 bit environment , How to tell which?
We need to maintain both 32 bit and 64 bit versions in the future. If you do your job right, you will have only version to maintain, that will work on both 32 and 64-bit platforms. This is not affected by 32 vs 64 bit issues, but may be affected by byte order issues. Switching from long to int buys you nothing.

Yes.. you could very well run protected mode 64-bit stuff _launched from DOS_, just as you do 32-bit stuff. But keep in mind, that's an ugly hack. And that would require at least a minimal bit of 64-bit support in the 32-bit OS, at least to manage the proper save/restore of registers on task swaps, interrupts,

Intel's IA64 standard is completely incompatible with the AMD x86-64 standard, costs much more, provides very poor performance with existing 32-bit software, According to AMD's technical documents on their website, x86-64 has full support for 16-bit, 32-bit, and 64-bit applications running concurrently.
