A terminal apparatus of a communication system is provided with an MAC section (bidirectional communication apparatus), a PHY section, a tuner, and a back-end section. The MAC section comprises a downstream data processing block having a function of substituting for a portion of the process of the CPU, a upstream data processing block having a function of substituting for a portion of the process of the CPU, a bus data arbitration processing block, a CPU bus, the CPU, and a storage apparatus. The downstream data processing block and the upstream data processing block perform direct data transmission/reception while bypassing the CPU bus.
