+The !VciDspin interconnect is a low-cost, distributed network on chip, with a 2D mesh topology,
 providing the system designer a fully scalable bandwidth.
-It is composed of three components :
+It has been designed for shared memory clusterized, multi-processors architectures. 
+It supports the GALS  (Globally Asynchronous Locally Synchronous) approach.
+It implements a packet switching network, with a wormhole routing strategy, for low latency. 
+
+In order to avoid dead-locks for VCI command/response trafic it is strongly recommended to
+use two fully independent networks for the command packets and response packets: Each sub-system must contain the following hardware components:
+
+ * a VCI-DSPIN initiator wrapper
+ * a VCI-DSPIN target Wrapper
+ * a dedicated router for the command packets
+ * a dedicated router for the response paquets  
+ 
+A DSPIN network instanciates the three following components :
  * [wiki:Component/VciDspinInitiatorWrapper VciDspinInitiatorWrapper] : A VCI-DSPIN protocol converter for a VCI initiator.
  * [wiki:Component/VciDspinTargetWrapper VciDspinTargetWrapper] : A VCI-DSPIN protocol converter for a VCI target.
