// This file define a generic TSAR architecture.
// The physical address space is 40 bits.
//
// The number of clusters cannot be larger than 256.
// The number of processors per cluster cannot be larger than 8.
// 
// - It uses four dspin_local_crossbar per cluster as local interconnect 
// - It uses two virtual_dspin routers per cluster as global interconnect
// - It uses the vci_cc_vcache_wrapper 
// - It uses the vci_mem_cache
// - It contains one vci_xicu per cluster.
// - It contains one vci_multi_dma per cluster.
// - It contains one vci_simple_ram per cluster to model the L3 cache.
//
// The communication between the MemCache and the Xram is 64 bits.
//
// All clusters are identical, but the cluster 0 (called io_cluster), 
// contains 6 extra components:
// - the boot rom (BROM)
// - the disk controller (BDEV)
// - the multi-channel network controller (MNIC)
// - the multi-channel chained buffer dma controller (CDMA)
// - the multi-channel tty controller (MTTY)
// - the frame buffer controller (FBUF)
//
// It is build with one single component implementing a cluster,
// defined in files tsar_xbar_cluster.* (with * = cpp, h, sd)
//
// The IRQs are connected to XICUs as follow:
// - The IRQ_IN[0] to IRQ_IN[7] ports are not used in all clusters.
// - The DMA IRQs are connected to IRQ_IN[8] to IRQ_IN[15] in all clusters.
// - The TTY IRQs are connected to IRQ_IN[16] to IRQ_IN[30] in I/O cluster.
// - The BDEV IRQ is connected to IRQ_IN[31] in I/O cluster.
// 
// Some hardware parameters are used when compiling the OS, and are used 
// by this top.cpp file. They must be defined in the hard_config.h file :
// - CLUSTER_X        : number of clusters in a row (power of 2)
// - CLUSTER_Y        : number of clusters in a column (power of 2)
// - CLUSTER_SIZE     : size of the segment allocated to a cluster
// - NB_PROCS_MAX     : number of processors per cluster (power of 2)
// - NB_DMA_CHANNELS  : number of DMA channels per cluster (< 9)
// - NB_TTY_CHANNELS  : number of TTY channels in I/O cluster (< 16)
// - NB_NIC_CHANNELS  : number of NIC channels in I/O cluster (< 9)
// 
// Some other hardware parameters are not used when compiling the OS,
// and can be directly defined in this top.cpp file:
// - XRAM_LATENCY     : external ram latency 
// - MEMC_WAYS        : L2 cache number of ways
// - MEMC_SETS        : L2 cache number of sets
// - L1_IWAYS     
// - L1_ISETS    
// - L1_DWAYS   
// - L1_DSETS  
// - FBUF_X_SIZE      : width of frame buffer (pixels)
// - FBUF_Y_SIZE      : heigth of frame buffer (lines)
// - BDEV_SECTOR_SIZE : block size for block drvice
// - BDEV_IMAGE_NAME  : file pathname for block device 
// - NIC_RX_NAME      : file pathname for NIC received packets
// - NIC_TX_NAME      : file pathname for NIC transmited packets
// - NIC_TIMEOUT      : max number of cycles before closing a container

// General policy for 40 bits physical address decoding:
// All physical segments base addresses are multiple of 1 Mbytes
// (=> the 24 LSB bits = 0, and the 16 MSB bits define the target) 
// The (x_width + y_width) MSB bits (left aligned) define
// the cluster index, and the LADR bits define the local index:
//      | X_ID  | Y_ID  |---| LADR |     OFFSET          |
//      |x_width|y_width|---|  8   |       24            |
/////////////////////////////////////////////////////////////////////////
// General policy for 14 bits SRCID decoding:
// Each component is identified by (x_id, y_id, l_id) tuple.
//      | X_ID  | Y_ID  |---| L_ID |
//      |x_width|y_width|---|  6   |
