Abstract

　休止状態にあるホストプロセッサを頻繁に起動しないことにより、休止状態から稼働状態に遷移する際の時間的オーバヘッドを軽減することができるとともに、オーバヘッド時間に浪費する電力を抑制することができ、通信性能の向上を図ることができる受信装置。この装置では、通信インタフェース回路（１０１）は、ネットワークから受信した受信信号からパケットデータを抽出する。通信インタフェース制御回路（１０２）は、パケットデータが受信すべきパケットデータであるか否かを判定し、受信すべきパケットデータである場合に、割り込み信号を発行する。電源供給回路（１０６）は、電源を供給する。ホストプロセッサ（１０７）は、割り込み信号が入力した場合に、受信処理を含むプログラムを実行する。
