Memory Management Unit and Chipset

if 64 bit microprocessor can function with enhanced very large memory without the 64 bit nomer , then 32 bit microprocessors could be 16 bit .

Because software can simulate 32 bit math using carry over Math !!

If this discussion was started already ,, redirection link is useful.

PPC-64 bit is in planning.

Thanks

Hello,

Could you rephrase your question please? I don't have a clear picture of your concern yet.

I think the poster was saying that what pushed 32-bit out of spotlight , and 64-bit into spotlight ??

Because System Software Developer were complaining that value of 64-bit is not Null but Zero ; Perhaps Minus .

? AMD about 10 year ago announced the first 64-bit Design with Intel following within 1 year and 1.5 year ?

32-bit 386 has Cache , or Extended Memory , in the 486 . Then access to transient memory store or RAM does not require a 64-bit Microprocessor because

1

64-bit nomer or name is just the internal memory or Register Memory . Which is expensive .

2

Microprocessor have addressed to MMC or Memory Management Control ( a multiplex circuit ) .

3

Would of been doable has augment to System V as Monolithic Kernel and perhap maintained as Lithic Microkernel .
