This is already possible with the AS2.100, download our filter software and you can play with it...

I was actually thinking of using this nice family of FIR curves I'd designed. Is there any way I could write actual TI code and download it directly to the hardware?

This is not possible with the AS2.100, we use here another DSP. In the upcomming high end DSP, this could probably be possible becasue the product is based ond the TAS3108.

Hm. The thing has enough MHz to run 2800 clocks at 48 kHz sample rate, but efficient programming can't use it all because you run out of Data/Coefficient memory after executing about half the instructions. The math is really quite nice for IIR work, but would it have killed TI to put in a bit more data RAM?

Ah well, back to the drawing board.

It's not TI, but Analog Device...., we use the ADAU1702. We tried to get direct access to the DSP core to get the opportunity to write direct code, but AD couldn's serve us with that kind of support.

For FIR filtering or other diffcult stuff the next DSP system will be a much better platform.

What kind of filtering are you planning?

Actually, I was talking about the TAS3108. A quick glance at the instruction set and specs indicates my code could run out of memory pretty quickly.

As far as the filters go, they'd be two sets of FIRs for each channel, one about 800 taps long and the other about 80 or so, along with some FIR frequency response correction and perhaps some low frequency group delay correction as well. There are a few tricks I can do to reduce memory/CPU requirements, but they might not fit within 1K coefficient/ 1K data space.

I just ordered the Hypex AS200.1 (2 of them) About $780 shipped to the US these days, ouch!

I was going to transfer the money through my bank but their fees have increased.

Can I instead pay with paypal, how do I contact them to resolve this?

Our high end ersion will have optional TWO TAS3108 on board, perhapds this will make it easier...

I will change yoru order and send you a new order confirmation. Just transfer that amount by Paypal to info (at) hypexpro (dot) com

Jan, Thank you!!

Jan-Peter, how's the progress on the high end version?
