The IDT77V012 provides full header translation functionality along
with Data Path Interface (DPI) to UTOPIA Level 1 translation for switch
and DSLAM designs using the IDT SwitchStar. The address search and
replacement algorithm is performed using a VPI Tunneling or Full
Header format on 8, 12, 24, 28 or 32-bits of the header. This added flex-
ibility makes it suitable for both UNI and NNI formats. External memory
is required to perform the header translation (receive direction only),
which will support up to 16K connections using a 256K x 32 SRAM. The
new header, which is obtained as a result of the search, can be used to
overwrite the existing cell header in the receive path. A four byte TAG
can also be added to aid in routing cells.
The 77V012 also contains cell counters in the transmit and receive
direction. The counters can be used to provide detailed per VC
accounting information for a particular port.
Other features include In-Stream鈩?programming, which can be
utilized on either the DPI or UTOPIA interfaces, a Utility Bus interface for
accessing registers in the PHY device, and an interface for an
EEPROM.
