Can I transfer the application software from the e200z4 to the e200z2 core in MPC5748C

Now the CPU load in the core of E200Z4 is over, and the application layer software accounts for about 35% of the CPU load, and the application layer software contains a small number of floating point arithmetic. In order to solve the CPU load problem, can you transfer all the application layer software to E200Z2?

e200z2 does not have floating point unit, it is single issue core and it does not have D-cache and I-cache. Whether it offers enough performance for your use, it is application dependent.

My application used 35% CPU load in e200z4, can estimate in e200z2?

Unfortunately I don't have any performance numbers for e200z210, but it is similar core as e200z420 without data/instruction caches, but it running at half frequency.
