:> Have code that moves data from a known area in one address space to a corresponding area in another address space. This code executes multiple times per second. Code uses AR's and a MovePage instruction to get the data from one to the other, one page at a time. Since I know the real address location of the source and target of the move, I'm wondering how much overhead would be saved by doing this using real addresses as opposed to virtual, and using one MVCL instruction. Anyone have any history with this? Just because the pages are contiguous in virtual does not mean that they are contiguous in real. -- Binyamin Dissen <[email protected]> http://www.dissensoftware.com Director, Dissen Software, Bar & Grill - Israel Should you use the mailblocks package and expect a response from me, you should preauthorize the dissensoftware.com domain.
