Hello All! Where can I find a complete example of using C167 coprocessor, including its initialization and (espesially desired) chasing when results of calculation are ready for reading? There are some details obscure for me. Thanks.
So as far as I realise Keil compiler uses Taylor's series (or smth. similar) to compute sine, cosine, etc? And that's why these appear to be computed VERY slow. I can't see any optimisation here while there's coprocessor's Sin, Cos functions which take 600 and 700 ns, resp. And there's documented interface to coprocessor, but I've got some probs with it. So now the question is HOW to use coprocessor, not IF to use it ;) I don't care about x86's coprocessor capabilities. If I did, I wouldn't take C16x at all. So if there are manuals/examples, I'd gratefully take them. That's why I ask.
If you need a math coprocessor you just chose the wrong chip to begin with. The '51s are microcontrollers not microprocessors Erik
So the C16xs are, too. Or I don't understand your words...
So the C16xs are, too. Or I don't understand your words... Yes they are microcontrollers and for extensive math you need a microprocessor Have a look at the x86 series Erik
To erik: You mean that there's x86 processor in C16x controllers, and so what I have to do is find manual on x86 instructions? Could you kindly address me to where I can find it, please? Thanks.
