Great one, Thanks!
More stuff, less fear, less  hassle and less censoring? How 'bout it??. To discuss what YOU want to discuss instead of what others decide for you. It's possible...

But not at diystompboxes.com...... regrettably

The C6727 is a frighteningly powerful chip. At 300 MHz, you get 2400 MIPS/1800 MFLOPS.

1.8 GigaFLOPS!?!?!? 1.8 GigaFLOPS!!?!!?!

Just for a little skewed perspective, the Original Cray I supercomputers were rated at 166 MFLOPS.

The Eval board is $2K from Lyrtech but it comes with 8 channels of 192K 24bit A/D/A! :icon_twisted:

That's pretty incredible.  A person could do some seriously rad DSP with a 1.8 GFLOP chip at a very fast sample rate.  You could even do it in C and not worry about "wasted" instructions.  24 bits I once figured is about at the thermal noise floor assuming a 5V reference.  You would probably be quite accurately sampling analog noise.  I would have a really hard time believing somebody that thought 24 bit at 192k sounded "digital".

Get a whole bunch of RAM and you would have an incredible FX processor platform.  It's all just a simple matter of programming.

P.S.
FLOPS, for you who are not familiar with DSP, means FLoating point Operations Per Second

Here's a much more "in depth" PDF than the one posted at the start of the thread. :)
