Logical and physical address with MMU on? -

-



i'm having doubts how kernel physical , logical addresses handled mmu. i'll try explain question doing example. let's doing assumption on arm architecture.

the system starts mmu off, addresses pass inside cpu physical. before enable mmu make page table our physical addresses mapped @ virtual addresses physical address + 0xc0000000. after turn on mmu. of clear. questions start:

since in pipeline architecture let's instruction after load address 0x8000. knowledge here should have page fault since mmu doesn't find address anywhere inside page table, it's invoked page fault handle situation. if we've set interrupt vector, inside there's branch physical address, mmu doesn't find address , fall unavoidably in endless loop. missing?

i have many .npy (numpy) , .json files saved in s3, need download , load these files. for json files downloading files , loading dictionary using following code: obj = s3.object(bucket, key) response = obj.get() body = response['body'].read().decode('utf-8') data = json.loads(body) that way avoid writing .json file disk , reading it. now want same .npy files, equivalent? currently downloading file, saving temp file on disk , loading np.load avoid if possible. following https://stackoverflow.com/a/28196540/3509999 : obj = s3.object(bucket, key) io.bytesio(obj.get()["body"].read()) f: # rewind file f.seek(0) arr = np.load(f) wiki
