GENERAL DESCRIPTION
The FASTcard 2 is a PC/AT-based, single MAC, dual at-
tachment FDDI concentrator board-set, based on
AMD's second generation SUPERNET 2 FDDI devices.
The board set consists of two board types: a dual attach-
ment station (DAS) board, and a master ports (MP)
board. The basic 2-board set configures a 4-station dual
attachment concentrator. By adding additional MP
boards, 8-station or 12-station dual attachment concen-
trators can be configured.
The FASTcard 2 evaluation board uses AMD's proven
SUPERNET 2 hardware solution to operate as an FDDI
compliant node. The kit can be used as a model design
to base new FDDI development on or it can be used to
debug and test your existing system. The hardware and
software have been tested and revised to make them
more robust and interoperable with multiple vendors'
equipment. In fact, you can use the FASTcard 2 tools to
check your own system for interoperability.
The FASTcard 2 provides complete hardware and soft-
ware tools to implement a FDDI Dual Attachment Sta-
tion (DAS) or a concentrator. Along with the board, the
DAS card comes with pDEMO 2 ( a user interface appli-
cation), user manuals, SUPERNET 2 Data Book, ribbon
cable and connectors, and 10 ft fiber optic cables and
connectors. The Master Port board(s) may be pur-
chased separately to configure a 4, 8 or 12 station dual
attachment concentrator.

HARDWARE
The FASTcard 2 hardware consists of two main sec-
tions; the FDDI station logic and the associated inter-
face logic. The FDDI station logic consists of the
SUPERNET 2 chip set, the buffer memory, and the fiber
optic transmitter/receiver. The chip set performs the
buffer memory management tasks in addition to the
MAC and PHY layer functions. The buffer memory on
the FASTcard 2 hardware consists of 128K bytes organ-
ized as 32K x 36 bits. Buffer memory control logic pro-
vides the host CPU with direct access to the FDDI buffer
memory via the host DMA interface of the FORMAC
Plus (Am79C830A).
The interface logic consists of the AT bus interface, the
host-buffer memory interface, counter and interrupt
logic, Connection Management (CMT) logic, and FDDI
configuration hooks and control logic. The CMT logic is
responsible for gathering connection statistics of the
network to report them to the station. The DAS board
provides interface signals to additional MP cards when
constructing a concentrator. The DAS board makes use
of the AT's processor as the host and node controller.
