Just for completenessвЂ¦ a Double-Precision vector in a 128-bit vector would contain a вЂњmeaslyвЂќ two values. Ok, take the set of number Дespite the second set not including every number of the first set, it _STILL_ has a cardinality that is 100 times larger.Дespite AltiVec not having Double Precision support, the number of supported opcodes, and the capabilities of it, still far outweigh the pain-in-the-butt, which are the MMX/SSE/SSE2 hacks.

вЂњWithout even vector DP support, how on Earth can it be вЂhundreds of times betterвЂ™? ItвЂ™s useless for the code I write, for instance.вЂќ Oh, and the current cvs took out everything that was making it go faster than without altivec, as backbone is being written in. If you compile it with the generic core, you will eventually be able to run it on any architecture, and single step through instructions. PearPC will never use вЂњhacksвЂќ that will speed up MacOSX, at the cost of providing support to even the hobbiest of OSes. While MoL will only run on a PowerPC processor, PearPC will eventually run on any processor, and host any OS. While MacOnLinux is a Macintosh Virtualizer. PearPC is a PowerPC Architecture Emulator. Even scalar emulation of the AltiVec core was showing some limited performance gains. Until then, the speed will suffer, but this is an initial вЂњit worksвЂќ release, not an optimized release build.ДЄlthough, due to the fact that AltiVec instructions generate no exceptions, and sets no condition flags (except saturate) the cost of emulation is significantly lower.ДЄltiVec is also used extensively by the OSX operating system for drawing, and copying memory. What mapping that can be done, will eventually be done. Until the PearPC developers can produce an emulator that doesnвЂ™t hinder performance I would advise not to waist your time on this emulator software.ДЄltiVec is hundreds of times better than MMX/SSE/SSE2. In a business where time impacts the dollar (ie: animation, rendering, compositing, editing) using an emulator which slows work being done really saves you nothing.

The software also runs on current hardware in studios which saves even more money instead of purchasing turnkey systems from Apple. Such software doesnвЂ™t require emulation or require purchasing a G5 because the software has been ported to Linux. After all studios have used Linux and open source technology for years. Until that time many studios are satisfied running software such as Maya and Shake on Linux.

If I want to use Maya and Shake on OSX then IвЂ™ll purchase a G5 system. One of the reasons I switched to Linux is because of the highend software I use and performance gained compared to that of using Windows.

are very fast, especially with OS that support bus-mastering (Linux, Darwin, Mac OS X do)вЂќ вЂњWhile the CPU emulation may be slow (1/500th or 1/40th, see above), the speed of emulated hardware is hardly impacted by the emulation the emulated hard-drive and CDROM e.g. The question I have is why would anyone want an emulator such as PearPC that makes the client OS as well as applications run at a poor speed? This is very counter productive to use such a product.

Granted, altivec got it right the first time, where Intel needed MMX (64bit integer only SIMD that overlayed the floating point registers, making mixed code a pain), SSE (128bit SIMD in a seperate register set, but lacked double precision fp operations) and SSE2 (finally a full SIMD implementation).

Look at most game emulators or movie players) but Intel has had SIMD for years. YouвЂ™re right in that you need a special compiler to take advantage of it (unless you hand code the assembly, like many people do with Intel MMX. Unless vector ops take different clock cycles to complete than the floating point unit you will get (# of chunks in vector unit)x speed up over just integer or floating point. Floating point speed up will be generally 2 or 4 (32bit single precision or 64bit double precision). 8bpp, into a 128bit register, means you can do 16 additions at a time.

Vector units can make certain operations very fast. The G4 had 32bit registers for integer, and the G5 has 64bit registers.
