Family Description
The Merlin
Fibre Channel Core Family is comprised of
three components:
l
Fibre Channel Engine (FCE)
l
Bolt-On Modules
l
Loop Port Controller (LPC)
Fibre Channel Engine
The Fibre Channel Engine is responsible for frame
transmission and reception, exchange management, and
inter-module traffic management. It performs all the
processing required to concurrently transmit and receive
frames at the full Fibre Channel data rate. It also
automates SCSI command processing, generating the
required data, control and status frames. Supports
multiple concurrent commands (exchanges).
Bolt-On Modules
The Bolt-On Modules are Transmit Buffer, Receive Buffer,
Transmit Prioritizer, BB (Buffer-to-Buffer) Credit
Manager, Exchange Tables, TXB DMA Interface and RXB
DMA Interface. The Transmit Buffer and Receive Buffer
can be used if the system memory cannot guarantee
immediate full-bandwidth access. The Transmit
Prioritizer determines which exchange has the highest
priority to send frames. The BB Credit Manager
provides efficient buffer-to-buffer flow control on an
arbitrated loop. The Exchange Table RAM provides a
central data storage area for the Exchange Table used by
the FCE. The TXB DMA Interface and RXB DMA
Interface allow a DMA module to transfer data from
external storage directly to the FCE.
