4 parts:

might be not complete, left out stupid answers and braindead moments :)

was asked about the von neumann architecture? told something i could remember about cpus, was a weird discussion.

then about an ASIC. whats better about ASICs

is a von neumann cpu also an asic?

where to configurable devices lay in the scale of von neumann and asics?

why whould you use such devices? possible answers that I gave were:

rapid prototyping cost …?

PLD are?

Whats a PLA?

Implement the function a equals b on a PLA. gave a truth table. then sketched a PLA and showed how the funktion would be implemented on a PLA

Whats an FPGA? whats a coarse grained device, and how does it differ to an device made of luts. bit functions versus word level logic (i suppose something like this)

I was presented a function

``` abd + ~cd + ~a~bd + a ```

how many luts do you need to implement this?

was a bit wonky here, because i didn't a good look at the funktion and was a bit confused

what are the constraints?

told them the 3 principles forgot about the 4th, but remembered quickly

was shown 2 Partitions, both had constraint violations I needed to identify

Was shown the example from the lecture.

Where could you place a new module here?

Mark all maximal squares.

there would have been further questions, but we ran out of time.
