Quite a lot of solutions to choose from indeed...

Although I've always had the feeling that these Xilinx / Altera thingies
required quite a lot of engeneering & time, like development platform,
learning curve, development time etc. and because of their packages
weren't that easy to implement on the DIY project & PCB.
I might be wrong but I had the feeling that a 16x16 multiplier was a more
attractive solution, or at least featured the right balance between type of

package, ease of implementation etc in a DIY context... Haven't checked
the price yet though...
