Title: Input-output processing on a remote integrated circuit chip

Abstract

An electronic device includes a first integrated circuit chip including a processing functional block, and a second integrated circuit chip including an input-output (IO) functional block. The IO functional block performs one or more IO processing operations on behalf of the processing functional block in the first integrated circuit chip. The first integrated circuit chip lacks at least some elements of the IO functional block, so that the processing functional block is unable to perform corresponding IO operations without the IO functional block.
