Another question. Diablo had support for counters, which is not in Lassen. Do we need additional support for counters?

It would be great if we could support them. There are a lot of counters in jeff's applications. I do not think these were tested much (if at all) in Diablo.

We have support for 32-bit Add (carry-in), but we are not supporting Breakpoints/IRQ, counter mode, and a dynamically enabled register.

There are workarounds for qualfiied register by using another PE to for the enable Mux.
Workarounds for 32-bit mul is that we can use more PE tiles
Workaround for counter mode is to just use multiple PE tiles
