Re: [Xylo-SDR] Firewire, DSP and FPGA on one module

The board that Leon is laying out uses the bottom end Cyclone II chip, it has thirteen 18 bit multipliers on board and 2.5X the amount of logic, and 3X the amount of RAM compared to the Xylo. That board aught to have plenty left to play around with, and  with the multiplier chips it aught to handle some of the math, at least to start experimenting.

It usually takes 4 18 bit multipliers to implement a 36 bit multiplier, you could have 3 36 bit multipliers cranking out data that ought to be good for something.

I'm no expert either, but I have vision issues that make it very hard for me to build with SMT, but with this device, you wire the inputs, you wire the outputs, and whatever happens in-between does not require a soldering iron.

Hi Cecil,

I let you (or anybody else) wet your feet with Xylo first. Then I
possibly jump directly to my own radio hardware design, if no
satisfactory solution available anywhere.

I am no expert, just a hardware radio tinkerer since my first one tube
receiver in 1947. With this experience I have noticed that it is easier
to improve the good work of others than starting from the scratch.
Another reason for not starting just now is my stressing consulting
project, at least until February.

Thanks everybody for your hard work, it will be a pleasure to exploit
it!

I fail to see why doing the same thing over and over and getting the same results every time is insanity: I've almost proved it isn't; only a few more tests now and I'm sure results will differ this time ...
