The MUAD "Harmony" Ternary CAM is a fast look-up
table device supporting ternary (0, 1, don't care) elements
for networking and communication applications. Harmony
is a member of MUSIC Semiconductors RouteCAM
family.
The organization of the Harmony 2M part is 16K x 136
bits, and the 1M part is 8K x 136-bit wide, with
double-word and half-word options.
Harmony is ideally suited for high-speed, high-capacity
functions, including Ethernet and IP address search, data
compression, pattern recognition, cache tags,
high-bandwidth address filtering, and fast routing search
tables. These functions also include privileged, secured, or
encrypted packet-by-packet information utilized in
high-performance Internet equipment such as switches,
firewalls, bridges, and routers.
The flexibility of the Harmony device allows the creation
of multiple search tables within the same device. It
compares, simultaneously, the desired information (data)
against an entire, pre-stored, array of addresses, providing
a performance advantage by reducing search times an
order-of-magnitude over typical binary or tree-based
search algorithms. The Harmony device can be designed
into many applications, but it is particularly well suited to
perform highly intensive search operations.
