    1212The GIET-VM uses three 32 entries interrupt vectors (one interrupt vector for each interrupt type).
    1313
    14 The CXU component is a replicated peripheral: it must exist one XCU per cluster, and each one can contain several channels:
    15 The number of XICU channels is equal to NB_PROCS_MAX, because there is one private XCU channel per processor in a cluster.
     14The XCU component is a replicated peripheral: it must exist one XCU per cluster, and each one can contain several channels (one channel per output IRQ).
     15
     16The number of XICU channels must be larger or equal to (NB_PROCS_MAX*IRQ_PER_PROCESSOR), even if the GIET-VM uses only one channel per processor (index = IRQ_PER_PROCESSOR * lpid).

    1718The virtual base address of the segment associated to the component is:
