+| CHStone : a suite of benchmark programs for C-based High-Level Synthesis |
+| ======================================================================== |
+|                                                                          |
+| * Collected and Modified : Y. Hara, H. Tomiyama, S. Honda,               |
+|                            H. Takada and K. Ishii                        |
+|                            Nagoya University, Japan                      |

+| * Remark :                                                               |
+|    1. This source code is modified to unify the formats of the benchmark |
+|       programs in CHStone.                                               |
+|    2. Test vectors are added for CHStone.                                |
+|    3. If "main_result" is 0 at the end of the program, the program is    |
+|       correctly executed.                                                |
+|    4. Please follow the copyright of each benchmark program.             |
