1+==============================================================================
2+ Hyper Operating System V4 Advance
3+ 用サンプル
4+
5+ Copyright (C) 2008-2011 by Project HOS
6+==============================================================================
7+
8+
9+＜概要＞
10+ お題は例によって、「哲学者の食事の問題」です。
11+ 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、
12+動作します。
13+
14+ 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
15+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
16+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
17+空腹状態になります。
18+
19+
20+＜環境＞
21+ XILINX EDK12
22+
23+＜使い方＞
24+ GNU make が利用できる環境で
25+
26+ gcc の場合： hos-v4a/sample/mb/mb_v8/gcc
27+
28+ に移動して、gmake
29+
30+ と打ち込みます。
31+
32+ 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。
33+
34+ 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
35+シリアルに表示されれば成功です。
36+
37+＜備考＞
38+ gmake MEMMAP=ram
39+
40+ 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。
41+ 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。
