This python script generates the "arch_info.bin" file required by the ALMOS-MK # operating system bootloader and describing the target hardware architecture. # It uses an architecture specific, python script that must be called "arch_info.py". # # The source directory containing the "arch_info.py" file and the destination directory # to store the "arch_info.bin" file are defined by parameters on the command line: # --arch=string : path to directory containing the "arch_info.py" file # --bin=string : path to directory store the "arch_info.bin" file # # As the target architecture is generic, the following hardware parameters can be # defined on the command line: # --x_size=int : number of clusters in a row # --y_size=int : number of clusters in a column # --nb_cores=int : number of cores per cluster # --nb_ttys=int : number of TTY channels # --nb_nics=int : number of NIC channels # --nb_cmas=int : number of CMA channels # --fbf_size=int : frame buffer width & heigth # --ioc_type=string : can be IOC_BDV , IOC_HBA , IOC_SDC , IOC_SPI # --mwr_type=string : can be MWR_GCD , MWR_DCT , MWR_CPY # --io_cxy=int : IO cluster identifier # --boot_cxy=int : boot cluster identifier # --cache_line=int : number of bytes in a cache line # # The following parameters can be used to generate the optional "hard_config.h" file, # that is required to configurate the SystemC virtual prototype, and the "arch_info.xml" # file for debug. # --hard=string : path to directory to store the "hard_config.h" file # --xml=string : path to directory to store the "arch_info.xml" file # ######################################################################################### import sys from arch_classes import * from optparse import OptionParser ################################################################################### #
