Message:

tsar_generic_leti: Using the new P_WIDTH constant from hard_config.h

• This constant is used in the clusters to compute the procesor id which now is: (((x << Y_WIDTH) + y) << P_WIDTH) + lpid

• Introducing the p_width constant in the arch.py files

• trunk/platforms/tsar_generic_leti/top.cpp (modified) (4 diffs)
