Using CPU Command I can see this information:

ICacheL2Size 262144
DCacheL2Size 262144

It seems OK, L2 caché 512K

ICacheL3Size 1048576
DCacheL3Size 1048576

What means? 2 MB L3 Caché
Freescale website says MC7447 lacks L3 cache.

Any info?
Thanks

This output is just all wrong.
1st)
All never G4 dont have any level 3 cache anymore.
As of today the level 3 cache gives little advantage over normal memory.

2nd) The level2 cache is not seperated in instruction and data.

It seems M7447 has suport for up to 2MB L3 cache
so surely cpu command output is on the wrong side.
