MMX and 3DNOW!

[Tiagocg]

Include support for MMX and 3DNow! (like AMD) in the source code of the Chankast makes it more fast? Just an idea. :blush: Sorry for my English, I am from Brazil :alien2:

I'm sure MMX is in use along with SSE (essentially a more advanced 3DNow!). SSE being FPU SIMD and MMX being Integer SIMD. Besides, any CPU which doesn't support SSE is likely to be too slow to run Chankast acceptably anyway.

What About Athlon Thunderbird 1.4 Mhz, I don't think it's too slow and it dosen't support SSE.

It wouldn't run horrible I admit, but probably not defined as playable.

1.4 Mhz?

 

[Falcon4ever]

everything below 2 ghz is slow

Haha.. my 1.8GHz Tualatin PIII runs chanka very very well. What are you on about?

Guru64.. make a damn inference, jesus. He means GHz. No need for dumb posts like that.

the SH4 has a stronger FPU unit clock-for-clock than the x87 math co-processor inside the x86. SSE is being used used because it works on FPU operations, MMX only deals with integer operations. Most likely 3dnow is being ignored because SSE is more prevelant (p3,p4,AMD XP and better) and SSE is available on hardware which can run Chankast at near full speed. Implementing 3dnow is alot of extra work for nothing -- even if were supported all the AMD-Tbird processors still too underpowered to run chankast at full speed.

looking at the instruction set, 3dnow seems simpler to implament than SSE, i spose something to detect different instruction sets would prove an advantage, maybe implamenting SSE2 as well? a lot of P4 users about and Athlon 64 users are growing too.

I wait with much anxiety that chanka twirls in some PC with less of 1ghz after all if it ja this twirling in its version alpha well, is of if waiting that it is each better time and that he twirls in pc's less powerful

Sorry my bad english, i from brazil, a example of tiagocg

I think it's more relistic to see consistant framerates on computers 2.4Ghz and higher, but getting Chankast to run at near full speed on a 1Ghz computer? you have to be day dreaming!
