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#
11# It generates the files required for hardware and software compilation:
12#
13# 1) The "hard_config.h" file is used to generate the top.cppnetbsd file (hardware),
14#    and to compile the tsar_preloader.elf, the GietVM boot.elf and kernel.elf files.
15#
16# 2) The optionals "map.bin" and vsegs.ld" files are used to configure the GietVM.
17#
18# 3) The optional "netbsd.dts" file can be used to configure NetBSD.
19#
20# 4) The optional "arch.bib" file can be used to configure ALMOS.
21#
22# 5) An optional "map.xml" file can be generated for debug.
23#######################################################################################
24# The hardware parameters  are:
25#  - x_size    : number of clusters in a row
26#  - y_size    : number of clusters in a column
27#  - nprocs    : number of processors per cluster
28#######################################################################################
29# The supported platforms are:
30# - tsar_generic_iob
31# - tsar_generic_leti
32#######################################################################################
33# The supported parallel applications are:
34# - sort (one thread per processor)
35# - transpose (one thread per processor)
36# - convol (one thread per processor)
