/////////////////////////////////////////////////////////////////////////////
// History
// - 25/04/2008
//   The existing vci_xcache component has been extended to include 
//   a VCI target port to support a directory based coherence protocol.
//   Two types of packets can be send by the L2 cache to the L1 cache
//   * INVALIDATE packets : length = 1
//   * UPDATE packets : length = n + 2   
//   The CLEANUP packets are sent by the L1 cache to the L2 cache, 
//   to signal a replaced cache line.
// - 12/08/2008
//   The vci_cc_xcache_wrapper component instanciates directly the processsor 
//   iss, in order to supress the processor/cache interface.
//   According to the VCI advanced specification, this component uses one 
//   word VCI CMD packets for MISS transactions, and accept one word VCI RSP
//   packets for Write burst  transactions.
//   The write buffer has been modified to use the WriteBuffer object. 
//   A VCI write burst is constructed when two conditions are satisfied :
//   The processor make strictly successive write requests, and they are
//   in the same cache line. The write buffer performs re-ordering, to
//   respect the contiguous addresses VCI constraint. In case of several
//   WRITE_WORD requests in the same word, only the last request is conserved.
//   In case of several WRITE_HALF or WRITE_WORD requests in the same word,
//   the requests are merged in the same word. In case of uncached write
//   requests, each request is transmited as a single VCI transaction.
//   Both the data & instruction caches can be flushed in one single cycle.

      // The DCACHE FSM controls the following ressources:

      // - r_dcache_fsm_save
      // - r_dcache (data cache access)
      // - r_dcache_addr_save
      // - r_dcache_wdata_save
      // - r_dcache_rdata_save
      // - r_dcache_type_save

      // - dreq & drsp structures for communication with the processor
      //
      // 1/ EXTERNAL REQUEST : 
      //    There is an external request when the tgt_dcache req flip-flop is set,
      //    requesting a line invalidation or a line update. 
      //    External requests are taken into account in the states  IDLE, WRITE_REQ,  
      //    UNC_WAIT, MISS_WAIT, and have the highest priority :
      //    The actions associated to the pre-empted state are not executed, the DCACHE FSM
      //    goes to the CC_CHECK state to execute the requested action, and returns to the
      //    pre-empted state.
      //  2/ PROCESSOR REQUEST : 
      //   In order to support VCI write burst, the processor requests are taken into account
      //   in the WRITE_REQ state as well as in the IDLE state.
      //   - In the IDLE state, the processor request cannot be satisfied if
      //   there is a cached read miss, or an uncached read.
      //   - In the WRITE_REQ state, the request cannot be satisfied if
      //   there is a cached read miss, or an uncached read,
      //   or when the write buffer is full.
      //   - In all other states, the processor request is not satisfied.
      //
      //   The cache access takes into account the cacheability_table.
      //   In case of processor request, there is five conditions to exit the IDLE state:
      //   - CACHED READ MISS => to the MISS_WAIT state (waiting the r_miss_ok signal), 
      //     then to the MISS_UPDT state, and finally to the IDLE state.
      //   - UNCACHED READ  => to the UNC_WAIT state (waiting the r_miss_ok signal), 
      //     and to the IDLE state.
      //   - CACHE INVALIDATE HIT => to the INVAL state for one cycle, then to IDLE state.
      //   - WRITE MISS => directly to the WRITE_REQ state to access the write buffer.
      //   - WRITE HIT => to the WRITE_UPDT state, then to the WRITE_REQ state.
      //
      // Error handling :  Read Bus Errors are synchronous events, but
      // Write Bus Errors are asynchronous events (processor is not frozen).
      // - If a Read Bus Error is detected, the VCI_RSP FSM sets the
      //   r_vci_rsp_data_error flip-flop, and the synchronous error is signaled
      //   by the DCACHE FSM.
      // - If a Write Bus Error is detected, the VCI_RSP FSM  signals
      //   the asynchronous error using the setWriteBerr() method.
