    1010The target architecture is clusterised: the physical address space is shared by all cores, but it is physically distributed, with one physical memory bank per cluster, and the following assumptions:
    11  * The physical addresses - also called extended adresses - are 64 bits encoded.
     11 * The physical addresses are 64 bits encoded.
    1212 * The max size of the physical address space in a single cluster is defined by the CONFIG_CLUSTER_SPAN configuration parameter, that must be a power of 2. It is  4 Gbytes for the TSAR architecture, but it can be larger for Intel based architectures.
    1313 * For a given architecture, the physical address is therefore split in two fixed size fields : The '''LPA''' field (Local Physical Adress) contains the LSB bits, and defines the physical address inside a given cluster. The '''CXY''' field (Cluster Identifier Index) contains the MSB bits, and directly identifies the cluster.
