My bad, some GNU toolchain for Tricore will have been used, why do you want to know?

I would like to know what hardware/software is required to do RAM logging on EDC17, the informations which are available on the web are not much friendly for non experienced people.

I the RAM logging is done (no idea why did I wrote about that in this thread), but back to topic got a question regarding ASM:
Code:
mul32           e0, d0, d2

Ex register is 64bit, but what does mul32 mean in that case? Will it strip 64bit result to 32bit and put it to d0 without touching d1, or maybe different way?

Anyone know where the jump table is for the logging is on any med17's?

EDIT: Figured it out.  Most things that you'd want to log for tuning or code hacks already exists, can all be adjusted in WinOLS no need for IDA.

mul32 is a 32 bit instruction length. When you assemble with Tricore you just write mul.
