Thanks for your reply.

No I don't want to change the width of the processor from 32b to 36b. It's just that the algorithm needs 36b and I'm not sure how I can calculate with 36b on a 32b processor. AFAIK on x86 ISA there is an int64_t type available though it's only a 32b processor. Therefore I thought that I could also use int64_t for my values in this case.

In the end the SW should be profiled and some slow components will be placed into their own HW accelerator. But before that I need to get the SW running.

I could use some real 64b processor but my university has some existing HW accelerators for the PULPissimo therefore I would like to use the same platform such that I can easily reuse them.
