Question:

What is the usage of exclusive access memory (EAM)?

 

Answer:

This is the memory area where simultaneous access by instructions (STRx, LDRx, STREXx, and LDREXx) from several CPU cores are excluded (the letter ‘x’ means the suffix of the bit range. “D”, “B”, and so on). This exclusion is used for multicore system.
