Changeset 271 for soft/giet_vm/giet_libs/stdlib.c

Timestamp:

Message:

• Bugfix: The ISR_SWITCH index should be NB_PROCS_MAX + local_pid. This is because the first NB_PROCS_MAX indexes on the XICU in each cluster are used for the WAKEUP software interrupts.

• Relocating the memcpy and memset functions into the giet_libs/stdlib.* files.

• Modification of the sort application to used 8 threads instead of
  4. Modifying the mapping files to distribute the 8 threads on the available processors. (Ex. When using 4 processors, each one executes 2 threads)

File:

• soft/giet_vm/giet_libs/stdlib.c (modified) (2 diffs)
