| 9 | # This python script generates the "arch_info.bin" file required by the ALMOS-MK |
|---|
| 10 | # operating system bootloader and describing the target hardware architecture. |
|---|
| 11 | # It uses an architecture specific, python script that must be called "arch_info.py". |
|---|
| 12 | # |
|---|
| 13 | # The source directory containing the "arch_info.py" file and the destination directory |
|---|
| 14 | # to store the "arch_info.bin" file are defined by parameters on the command line: |
|---|
| 15 | # --arch=string : path to directory containing the "arch_info.py" file |
|---|
| 16 | # --bin=string : path to directory store the "arch_info.bin" file |
|---|
| 17 | # |
|---|
| 18 | # As the target architecture is generic, the following hardware parameters can be |
|---|
| 19 | # defined on the command line: |
|---|
| 20 | # --x_size=int : number of clusters in a row |
|---|
| 21 | # --y_size=int : number of clusters in a column |
|---|
| 22 | # --nb_cores=int : number of cores per cluster |
|---|
| 23 | # --nb_ttys=int : number of TTY channels |
|---|
| 24 | # --nb_nics=int : number of NIC channels |
|---|
| 25 | # --fbf_size=int : frame buffer width & heigth |
|---|
| 26 | # --ioc_type=string : can be IOC_BDV , IOC_HBA , IOC_SDC , IOC_SPI |
|---|
| 27 | # --io_cxy=int : IO cluster identifier |
|---|
| 28 | # --boot_cxy=int : boot cluster identifier |
|---|
| 29 | # --cache_line=int : number of bytes in a cache line |
|---|
| 30 | # |
|---|
| 31 | # The following parameters can be used to generate the optional "hard_config.h" file, |
|---|
| 32 | # that is required to configurate the SystemC virtual prototype, and the "arch_info.xml" |
|---|
| 33 | # file for debug. |
|---|
| 34 | # --hard=string : path to directory to store the "hard_config.h" file |
|---|
| 35 | # --xml=string : path to directory to store the "arch_info.xml" file |
|---|
| 36 | # |
