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 glogals virtual segments)
13	# a set of 'Vspace' (one or several user applications)
14	# - A 'Cluster' contains a set of 'Pseg' (physical segments in cluster)
15	# a set of 'Proc' (processors in cluster)
16	# a set of 'Periph' (peripherals in cluster)
17	# - A 'Vspace' contains a set of 'Vseg' (user virtual segments)
18	# a set of 'Task' (user parallel tasks)
19	# - A 'Periph' contains a set of 'Irq' (only for XCU and PIC types )
20	########################################################################################
21	# Implementation Note
22	# The objects used to describe a mapping are distributed in the PYTHON structure:
23	# For example the psegs set is split in several subsets (one subset per cluster),
24	# or the tasks set is split in several subsets (one subset per vspace), etc...
25	# In the C binary data structure used by the giet_vm, all objects of same type
26	# are stored in a linear array (one single array for all psegs for example).
27	# For all objects, we compute and store in the PYTHON object itself a "global index"
28	# corresponding to the index in this global array, and this index can be used as
29	# a pseudo-pointer to identify a specific object of a given type.
