Abstract

　Ｌ（Ｌ＞１）種類のデータを逐次受信し、外部に送信するバッファ管理装置であって、データを受信する受信手段と、それぞれが、バッファ領域を含み、当該バッファ領域に記憶しているデータと同種データ用に割り当てられるＭ（Ｍ＜Ｌ）個のデータ記憶手段と、データの種類毎に、当該種類のデータの受信間隔に関する情報を記憶する間隔記憶手段と、それぞれが１つのデータ記憶手段と対応付けられ、対応するデータ記憶手段に最後にデータが記憶されてからの経過時間を計時するＭ個の計時手段と、制御手段とを備え、当該制御手段は、特に、受信データと異種データがいずれのデータ記憶手段にも割り当てられている場合には各計時手段が計時する経過時間と間隔記憶手段が記憶する情報に基づいて行った判定結果に応じて少なくとも１つのデータ記憶手段に記憶済のデータに代えて受信データを記憶するか、受信データを外部に送信する。
