Guitar effects - divi_78 - May 2 4:25:00 2005



HI guys
        I am working on a guitar effects DSP.This will include some 
modulation effects like 
chorus/phaser/flanger/reverb/delay/distortion.Ne one playing a guitar 
will understand what i am talking about.I am looking at a low cost
dsp 
some under $8.I am new to dsp and i would like you guys to help me
out 
in tring to select the right DSP.Basically i feel for a low cost i 
need a fixed piont DSP.Plus i need a DSP just enought to achive my 
goal.

Some of the more obscure DSP chips include (sorry I don't have part 
numbers off hand)--
	AKM has parts with both DSP and codec on board for a really minimal 
system (16 bits)

	Analog Devices has some very new parts in the DSP-DAC series. Some 
have on-board DACs, some don't. They're 24 bit.

	TI has a similar part to the Analog Devices ones mentioned above, 
meant for speaker EQ

	Alesis has one DSP chip that they developed I think for reverb, 16 
bit.

	The ADSP21xx family from Analog Devices always used to feature a low 
end part (ADSP2105?) 16 bit.

	You should check out low end SHARC 32bit FP parts (Analog Devices), 
too. At least in volume, they get pretty cheap.

	Some members of the Freescale (Motorola) DSP563xx get pretty cheap, 
too.

	And there are the 67xx TI floating point parts.

Good luck!

I think TI's  541x or 550x series is enough.
I have done on it.

You can find some examples of guitar effects in TI's site which are sent by Richard John
Sikora. There, are used C5510(fixed point) and C6711(floating point)DSKs. Unfortunately you
can't find a DSK at or under 8$.Ones above are 395$.
