| 8 | # This generic script maps one or several multi-tasks applications on a specific |
|---|
| 9 | # instance of the multi-processors/multi-clusters TSAR architecture. |
|---|
| 10 | # It generates the files required for hardware and software compilation: |
|---|
| 11 | # 1) The "hard_config.h" file is used to generate the top.cppnetbsd file (hardware), |
|---|
| 12 | # and to compile the tsar_preloader.elf, the GietVM boot.elf and kernel.elf files. |
|---|
| 13 | # 2) The optionals "map.bin" and vsegs.ld" files are used to configure the GietVM. |
|---|
| 14 | # 3) The optional "netbsd.dts" file can be used to configure NetBSD. |
|---|
| 15 | # 4) The optional "arch.bib" file can be used to configure ALMOS. |
|---|
| 16 | # 5) An optional "map.xml" file can be generated for debug. |
