Where to get PurePath Studio

[berni8k]

Does anybody know where to get TIs PurePath Studio or actually have it?

I couldn't get i anywhere. My plan is to use it for a TAS3208 DSP i cant relay do anything with the darn chip without the software. The software is free so why cant i get it anywhere gah!

It sure tock a long time but i FINALY got the software!

And i even got a simple filter to work inside the simulator.The software appears to be very powerful and the I2C interface to it looks like childsplay.

Now i need to build a board to test these puppys out for real!

So if you want to do audio processing like EQs and all that stuff do give TIs DSPs a try they seam so simple to use.

Be sure to keep us updated on your progress...

Well this is going to become a part of a amplifier with full digital control and a D-Class output stage. (6 chanell amp with TAS5630)

The user interface for it is planned to be blue LED illuminated capacitive touch pads behind glass along with a blue LCD and all this run by a dsPIC microcontroller. It would also monitor temperature sensors and power supply voltages and also control fans that could thorn on in case of a overheating danger.

What are also planed are expansion slots so i can add features to it like a FM tuner,USB, bluetooth, ethernet for streaming audio etc...

So its a whole lot more than the typical "buy a kit and throw it in a case" kind of amp

Wow! Talk about ambitious! Back in the day this was the kind of thing I would have dreamt of doing, never suspecting that I might achieve it. Now, I simply do not have the time to tackle something this big.

My own interest in DSP is for an active crossover with room correction (even this for me has issues of feasibility, especially since I am no longer working with electronics daily).

Good luck with your project.

Well with the TAS3208 its relay easy to make a crossover. Just drag in a filter block between an input and output. For making a simple crossover you dont even need a MCU on the I2C bus all you need is a I2C eeprom to store its program.

PurePath studio is what convinced me to go DSP. Before i was like how the hell am i gonna figure out how to write programs for DSPs and stuff. Until i saw that in PurePath the design is all graphical simply connecting function blocks. While looking simple it still has the versatility by giving you basic DSP blocks and a asm compiler for making your own blocks. Also it includes a simulator that can step trough the asembler code and even put WAV files to the inputs or outputs so you can listen to the result. You have to wait quite some time tho before it chews trough a few seconds of WAV tho.

The software dosent work on win7 so i ran it inside a VM running win2000 as i had it handy.

Hmmm... you are giving me hope. I'll check it out.

hello... my first post... hum
I am interrested as well, and saw that logitech sqeezebox boom is using TAS3204 my idea is:
it should be bossible to use this box for "real speaker" bi amping
the problem is reverse engineering the commands and adapt the Xover to your "real application"
all the hardware is done...
http://wiki.slimdevices.com/uploads/...dio_Design.pdf
but i would not like logitech updating my Xover...
I am not sure this is possible

any ideas?

Well its easy to create a crossover filter inside that DSP but the problem is that the DSP probably has a pile of stuff in it that support the original features so you would have to rebuild all that.

What can also be a problem is that the DSPs program is probably downloaded to it by the main CPU instead of from a EEPROM
