Functions
void	axi4liteProcessing (ap_uint< 32 > ctrlLink[64+16+16], stream< NalConfigUpdate > &sToPortLogic, stream< NalConfigUpdate > &sToUdpRx, stream< NalConfigUpdate > &sToTcpRx, stream< NalConfigUpdate > &sToStatusProc, stream< NalMrtUpdate > &sMrtUpdate, stream< uint32_t > &mrt_version_update_0, stream< uint32_t > &mrt_version_update_1, stream< NalStatusUpdate > &sStatusUpdate)
	Contains the Axi4 Lite secondary endpoint and reads the MRT and configuration values from it as well as writes the status values. It notifies all other concerned processes on MRT or configuration updates and is notified on status updates. More...
void	pMrtAgency (stream< NalMrtUpdate > &sMrtUpdate, stream< NodeId > &sGetIpReq_UdpTx, stream< Ip4Addr > &sGetIpRep_UdpTx, stream< NodeId > &sGetIpReq_TcpTx, stream< Ip4Addr > &sGetIpRep_TcpTx, stream< Ip4Addr > &sGetNidReq_UdpRx, stream< NodeId > &sGetNidRep_UdpRx, stream< Ip4Addr > &sGetNidReq_TcpRx, stream< NodeId > &sGetNidRep_TcpRx)
	Can access the BRAM that contains the MRT and replies to lookup requests. More...
void	pPortLogic (ap_uint< 1 > *layer_4_enabled, ap_uint< 1 > *layer_7_enabled, ap_uint< 1 > *role_decoupled, ap_uint< 1 > *piNTS_ready, ap_uint< 16 > *piMMIO_FmcLsnPort, ap_uint< 32 > *pi_udp_rx_ports, ap_uint< 32 > *pi_tcp_rx_ports, stream< NalConfigUpdate > &sConfigUpdate, stream< UdpPort > &sUdpPortsToOpen, stream< UdpPort > &sUdpPortsToClose, stream< TcpPort > &sTcpPortsToOpen, stream< bool > &sUdpPortsOpenFeedback, stream< bool > &sTcpPortsOpenFeedback, stream< bool > &sMarkToDel_unpriv, stream< NalPortUpdate > &sPortUpdate, stream< bool > &sStartTclCls)
	Translates the one-hot encoded open-port vectors from the Role (i.e. piUdpRxPorts and piTcpRxPorts) to absolute port numbers If the input vector changes, or during a reset of the Role, the necessary open or close requests are send to pUdpLsn, pUdpCls, pTcpLsn, and pTcpCls. More...
void	pCacheInvalDetection (ap_uint< 1 > *layer_4_enabled, ap_uint< 1 > *layer_7_enabled, ap_uint< 1 > *role_decoupled, ap_uint< 1 > *piNTS_ready, stream< uint32_t > &mrt_version_update, stream< bool > &inval_del_sig, stream< bool > &cache_inval_0, stream< bool > &cache_inval_1, stream< bool > &cache_inval_2, stream< bool > &cache_inval_3)
	Detects if the caches of the USS and TSS have to be invalidated and signals this to the concerned processes. More...
void	pTcpAgency (stream< SessionId > &sGetTripleFromSid_Req, stream< NalTriple > &sGetTripleFromSid_Rep, stream< NalTriple > &sGetSidFromTriple_Req, stream< SessionId > &sGetSidFromTriple_Rep, stream< NalNewTableEntry > &sAddNewTriple_TcpRrh, stream< NalNewTableEntry > &sAddNewTriple_TcpCon, stream< SessionId > &sDeleteEntryBySid, stream< bool > &inval_del_sig, stream< SessionId > &sMarkAsPriv, stream< bool > &sMarkToDel_unpriv, stream< bool > &sGetNextDelRow_Req, stream< SessionId > &sGetNextDelRow_Rep)
	Contains the SessionId-Triple CAM for TCP sessions. It replies to stram requests. More...
