ABSTRACT:
An IO processor includes an embedded central processing unit (CPU), a switch connected to the embedded CPU, an external CPU bus controller connected to the switch for optionally connecting to an external CPU, a first memory controller connected to the switch for connecting to a first memory, and a second memory controller connected to the switch for optionally connecting to a second memory. The IO processor may be connected to the external CPU, to the second memory, or be capable of connecting to external CPUs of different ranks, depending on the situation, so as to meet the cost considerations and the actual application requirements.
