I am quite surprised at the tack the whole discussion took. I was expecting more discussion on the fact that we actually had a company release a complete, commercial processor under the GPL. Regardless, let me remind everybody of one thing. Somebody has already done everything we are trying to do, before we have. Right now, the Sun processor is about the only large scale body of work from which we can use code. It doesn't matter what architecture approach we use or what we are doing. The first question in everybody's mind should be "Can I find someone else's code that does this so that we don't have to do it from scratch?" The second question should be "Can I legally use it?", followed by "If it doesn't work, why and is it easier to do it from scratch or change what I doing so it does work?". So maybe we don't use a full SIMD unit. Has anyone stopped to think that we now have access to a professionally developed hardware multiplier that we can study? Same thing for the adder. We don't have to take the whole SIMD unit. For that matter, we don't have to take all of any module in the processor. We have the ability to re-use any code we can. This is one of the biggest arguments for Open Source RTL code. We don't have to re-invent the wheel just because we want to build a car. We can use someone else's wheel and spend more time on making our care go better. > > An analog to digital board or box.

Maxim has some very nice ADCs that have 2Gsps+ sample rates, however getting them to sample anything over about 700Msps takes some real analog black magic on the front end. That said, a well designed analog daughter board could turn OGD1 into a very nice digital scope.
