Hi all.

These day, I got involved to use DTLB's functionality.

I'd like to know how many entries in DTLB has from Pentium to recent processor.

I searched the information from internet which mentioned that it's 64entires on pentium and 124entires on pentium 4.

But I wanna know it is right ?. please let I know.

thanks.

Andy ^^

Yes, Pentium 4 has 128 total DTLB entries, split between logical processors, when HyperThreading is in use.

Thanks for your quick response.

Could I know other processor's number of entires in DTLB(such as Pentium, Pentium Pro, Pentium 2) or the way to find the information.

I could not find that imformation at IA-32 software Developer's manual.
