What do we mean by 'write back current data' ? where does the External
Cache write it back ? How does writing back help ?
IMHO, before you disable the cache, you should first write back data
stored in it, other wise we will have data lost.CMIIW.
Oh okay so all operations that we perform are first recorded in the
cache and not in the memory. And if we have some write operation then
that needs to be 'written back' into the Main Memory or L2 ? What cache
are we referring to here.. ?
Thanks,
