KAD/FBM/102 1 channel Firewire Bus Monitor
1 channel Firewire Bus Monitor Parser
The KAD/FBM/102 is designed to monitor IEEE 1394 (FireWire) traffic, parse and tag packets, and distribute the monitored packet contents to other KAM-500 modules. The KAD/FBM/102 acts as a leaf in the FireWire bus topology. To all other nodes on the bus the link layer and transaction layer appear to be deactivated.
The bus monitor triple buffers up to 64 isochronous channels or asynchronous stream packets, with associated tags, i.e. the attributes which the bus monitor associates with each parsed packet (time, count, status and information words). Each buffer contains up to 1036 16-bit words, i.e. 1030 words of packet content, 3 words of timestamp, 1 word containing transaction number, 1 word containing information tag (INFO), and 1 word containing packet size. Triple buffering supports concurrent access to the packet being read, packet being received, and an interim packet.
The INFO word tag associated with each packet is used to indicate whether the packet is stale (buffer has been read before) or skipped (buffer has been overwritten). Data selection and content is based on a 64-bit filter mask, which allows the selection of each individual isochronous channel for parsing. Only traffic with transaction code 0xA is recognized. Bus configuration traffic, PHY packets, and asynchronous transactions are ignored. The KAD/FBM/102 is available only with a 52-way double density connector.
