Control Store
The Control Store is a RAM, which holds the program that the ME executes. It holds 4096
instructions, each of which is 40 bits wide. It is initialized by an external device (for example, the
internal Intel XScale core.) The Control Store can optionally be protected by parity against soft
errors.
