+==============================================================================
+ Hyper Operating System V4 Advance
+ 用サンプル
+
+ Copyright (C) 2008-2011 by Project HOS
+==============================================================================
+
+
+＜概要＞
+ お題は例によって、「哲学者の食事の問題」です。
+ ５つのタスクを哲学者、５つのセマフォをフォークに見立てて、
+動作します。
+
+ 哲学者はランダムな時間考え事をするとおもむろに両サイドの
+フォークを取って食事を始めます。しかし左右どちらかの哲学者が
+すでにフォークを使って食事をしていると、フォークが使えず
+空腹状態になります。
+
+
+＜環境＞
+ XILINX EDK12
+
+＜使い方＞
+ GNU make が利用できる環境で
+
+ gcc の場合： hos-v4a/sample/mb/mb_v8/gcc
+
+ に移動して、gmake
+
+ と打ち込みます。
+
+ 出来上がった、sample.bin をROMに配置して合成することで動作します。
+
+ ５人の哲学者がそれぞれ、考えたり、お腹を空かせたり、食事したりする様子が
+シリアルに表示されれば成功です。
+
+＜備考＞
+ gmake MEMMAP=ram
+
+ としすると、RAMを0番地に配置したモデルで sample_ram.bin を生成します。
+ ROM化せずにRAMをマッピングしてデバッグする場合にご利用ください。
