The execution time of every instruction with all possible addressing modes is listed in the M32C Series Software Manual. You can find it on the Renesas homepage.

But the times given in this manual are m,inimum times, assuming the instruction has been loaded completely to the instruction queue and the bus is free for data transfer.

To calculate execution times is quite difficult because you have to track the instruction queue status in parallel to your software. I would recommend to measure the execution time, and if the routine is time critical to experiment a little by inserting NOPs in order to modify the alignment of instructions to even or odd addresses.
