	11	# This file contains the python classes required to define a generic hardware
	12	# architecture for the ALMOS-MK operating system.
	13	# It handle 4 types of objects: clusters, cores, devices and irqs.
	14	# - The number of cluster is variable (can be one).
[6]	15	# - The cluster topology can be a 2D mesh or a simple 1D array.
[1]	16	# - The number of cores per cluster is variable (can be zero).
	17	# - The number of addressable devices per cluster is variable.
	18	# - The size of the physical memory bank per cluster is variable.
	19	# An adressable device can be a physical memory bank or a peripheral.
	20	# Each cluster cover a fixed size segment in physical address space,
	21	# that is defined by (PADDR_WIDTH - X_WIDTH - Y_WIDTH)
	22	#########################################################################################
	23	# Implementation Note:
	24	# The objects used to describe an architecture are distributed in the python structure:
	25	# For example the set of cores and the set of devices are split in several subsets
	26	# (one subset of cores and one subset of devices per cluster).
	27	# In the generated C binary data structure, all objects of same type
	28	# are stored in a linear array (one single array for all cores for example).
	29	# For all objects, we compute and store in the python object a "global index"
	30	# corresponding to the index in this global array, and this index can be used as
	31	# a pseudo-pointer to identify a specific object of a given type.
