Abstract: Provided are a modem chip for performing hybrid automatic repeat request (HARQ) processing, an application processor including the modem chip, and an operating method of the modem chip. A modem chip for receiving data of a codeword unit including a plurality of codeblock units includes a HARQ controller for controlling HARQ data of the codeword unit to be saved in an external memory based on an error detection result of the codeword unit, a HARQ mover for saving or fetching the HARQ data of the codeword unit in or from the external memory via a bus interface, and a HARQ combiner for combining retransmitted data with the HARQ data fetched from the external memory.

Abstract: A communication system configured to perform an address translation and a method of translating an address of the communication system are provided. The communication system configured to transceive a packet through a network includes a modem circuit configured to modulate the packet into a transmission signal to be transmitted to the network and demodulate a receiving signal from the network into the packet, and an address translation circuit configured to translate a network address of the packet, wherein the address translation circuit includes an embedded memory configured to receive a header of the packet from an external memory in which the packet is stored and store the header, a first translator configured to translate a format of the header, and a second translator configured to translate an address included in the header.
