Hi,
I'm using 8051 uC
I learned that since ROM is more slow than RAM, then part of the ROM is copied into RAM, to allow faster access for fetching instructions into the Instruction Register.
I have 2 questions please:
1. which part / content of the ROM is copied into RAM?
How can you tell it?
2. The copy of the ROM into RAM is done for fetching instuctions into the Program Counter?
Thank you very much.
