+ * Simple queuing trace buffer for debug data
+ * instantiatable in SP DMEM
+ *
+ * The buffer has a remote and and a local store
+ * which contain duplicate data (when in sync).
+ * The buffers are automatically synched when the
+ * user dequeues, or manualy using the synch function
+ *
+ * An alternative (storage efficient) implementation
+ * could manage the buffers to contain unique data
+ *
+ * The buffer empty status is computed from local
+ * state which does not reflect the presence of data
+ * in the remote buffer (unless the alternative
+ * implementation is followed)
