Preliminary

1.5.6. LINK- Rx

This block is on OHCI- 1394 boundary that is placed between the internal FIFO and LINK core. LINK- Rx is

responsible for adding the OHCI trailer data to the packet received by 1394 LINK core and storing into the

FIFO.

1.5.7. LINK- Tx

Similarly with LINK- Rx, this Link- Transmit section converts the OHCI packet stored in the FIFO by CPC into

the 1394 format packet for the LINK core.

1.5.8. LINK Core

This block generates the data CRC, header CRC, and also transmits self ID packets and controls packet

transmit and receive.

1.5.9. PHY

This block controls the 1394 serial bus protocol, including data encoding and bus arbitration.

1.5.10. bus manager

This block manages the cycle timer, generates interrupts, and holds the bus management CSRs.
