Hi all.
I have some problems with PowerPC syncronization instructions. In
particular I would know when sync and eieio instructions must be used.
I have the source code of a real time operating system for a single
processor board (MVME6100 with MPC7457) and I have notice the use of
sync, isync and eieio instructions. The question is: the
syncronization instruction should be used only in a multiprocessor
context, or not?
I have read the Reference Manual and the Programming Environments
guide but I'm confused.
Can someone explain to me why sync and eieio should be used or suggest
me a link?
Thanks!
