	10	# This file contains the classes required to define a mapping for the GIET_VM.
	11	# - A 'Mapping' contains a set of 'Cluster' (hardware architecture)
	12	# a set of 'Vseg' (kernel virtual segments mapping)
	13	# a set of 'Vspace' (several user applications).
	14	# - A 'Cluster' contains a set of 'Pseg' (all physical segments in cluster)
	15	# a set of 'Proc' (processors in cluster)
	16	# a set of 'Periph' (peripherals in cluster)
	17	# a set of 'Coproc' (coprocessors in cluster)
	18	# - A 'Vspace' contains a set of 'Vseg' (user virtual segments mapping)
	19	# a set of 'Task' (user tasks mapping)
	20	# - A 'Vseg' contains a set of 'Vobj'
[441]	21	# - A 'Periph' contains a set of 'Irq' (only for XCU and PIC types )
[319]	22	# - A 'Coproc' contains a set of 'Cpports' (one port per MWMR channel)
	23	##########################################################################################
	24	# Implementation Note
[411]	25	# The various objects used to describe a mapping are distributed in the PYTHON structure:
[319]	26	# For example the psegs set is split in several subsets (one subset per cluster),
	27	# or the tasks set is split in several subsets (one subset per vspace), etc...
	28	# In the C binary data structure used by the giet_vm, all objects of same type
[406]	29	# are stored in a linear array (one single array for all psegs for example).
	30	# For all objects, we compute and store in the PYTHON object itsel a "global index"
	31	# corresponding to the index in this global array, and this index can be used as
[319]	32	# a pseudo-pointer to identify a specific object of a given type.
