Abstract
A computer capable of performing communications processing using a protocol at high speed in simple and low cost configuration is provided. After an SD-RAM controller stores AV data inputted via an AV interface in an AV buffer circuit, a packet processing unit, for example, generates jumbo packet data of 32 KB. A PCI bus interface outputs data required for transmitting processing of the jumbo packet data to a CPU, and the CPU generates header data. A packet processing unit, according to the header data, splits the jumbo packet data and generates Ethernet packet data of a maximum of 1518 byte. The SD-RAM controller transmits the applicable data from a MAC circuit.
