NB: This is all a bit of a simplification, but you should get the overall idea. It's worth noting that many CISC chips nowadays are actually a CISC 'layer' that presents a CISC interface to the outside world for compatability (with older generations of the chip), but the actual execution cores are RISC, and the complex instructions are broken down for the RISC core to process. So you simply can't take advantage of much of the power contained in a CISC chip. Obecnie Virtual PC nie jest rozwijany, a jego nastpc jest Windows Virtual PC. More complex instructions that run slowly.ĬISC is quite easy to emulate on RISC, because even breaking down the complex instructions, those instructions execute quickly, and so there isn't much loss in performance (beyond the process of chopping up / converting the instructions).Įmulating RISC on CISC means that you can't really take advantage of the complex instructions. VirtualPC dla MacOS X nie jest ju produkowany i sprzedawany, poniewa firma Microsoft nie chce ju przeportowa obecnej wersji dla procesora PPC pod procesor Intela, który jest podstaw dzisiejszych Macintoshy. ![]() RISC machines get their speed from having few instructions but executing them very quickly. PPC's are simply a big challenge for x86 boxes, thanks to the difference in architecture. However, they only emulate the old Motorola chips, not the PPC's. can't really give him any recomendation right now other than to wait. a g5 would cost just a little more than that, have better performance and upgradeability (for ram, about the only thing he'd ever upgrade on the machine), but right now, they can't do what he needs, and there's no idea of how fast vpc will go when it *eventually* gets here.īummer of a place to be. In other words, Microsoft has discontinued Virtual PC because the company believes that it would not be profitable to develop a new version. that put me in a real hard place - he'd spend about 1100 upgrading that thing to what he's looking for (he wants much better performance in vpc), about 12 or 1300 for a new g4 (using my edu discount, possilby). ![]() ![]() that said, he came to me about a week ago and asked what it would take to max out and upgrade his g4 350 (agp). Also, you do not need this on the latest Windows Operating Systems since you can install free Hyper-V. The program doesn’t work for versions of Operating Systems earlier than Windows 7. I'd really like to know more - i have a friend who knows very little about computers (60+years old, took the dive a few years ago), and while he uses a mac, he also uses virtual pc cause one of his investing sites requires the use of ie 6.0, as well as a few of his programs for investing. The virtual PC for Windows is another freeware program for virtualization by Microsoft.
