ISSI Introduces High-Performance CAM-based Embedded Search IP
Solutions For Embedded Applications Incorporates 0.18um Process
Technology From SMIC SANTA CLARA, Calif., Feb. 24
/PRNewswire-FirstCall/ -- Integrated Silicon Solution, Inc. , a
leader inadvanced memory and network IC solutions, today launched
the second in a line of patented CAM-based embedded search IP for
communication networking systems. ISSI, the first company in the
industry to utilize a fine-grain CAMTile(TM) approach to achieve
unprecedented flexibility and performance in search co-processor
engines, is now making its CAMTile technology available for
embedded applications using the 0.18um process technology from
Semiconductor Manufacturing International Corporation (SMIC). This
offers the ideal solution for ASIC companies involved with
networking related businesses, communication chip, and system
companies who desire an embedded networking search function. The
SMIC 0.18um fine-grain CAMTile technology, along with the currently
available TSMC 0.18um CAMTile, enables unprecedented device
flexibility and performance. The CAMTile refers to a patent-pending
fine granularity intelligent embedded CAM (Content Addressable
Memory). The flexibility of the CAMTile architecture allows large
numbers of CAMTiles to be integrated onto a single chip, thereby
enabling a parallel, and scalable, search table implementation. Any
size CAM database table can easily be configured without any
performance degradation simply by grouping CAMTiles to efficiently
generate the desired width and depth CAM. In addition, the CAMTile
can achieve 100 million lookups per second per CAMTile. The
patented CAM cell construction wastes no memory cells and allows
the CAMTile to be configured as eithera 1Kx64 binary or 1Kx32
ternary CAM with maximum efficiency. The dual-port architecture
allows the CAMTile to read/write and search simultaneously, with
all hazard detection performed automatically. It supports many
other networking value-added functions, such as valid, aging, and
static entry bits, next-free-entry lookup, age refresh on search
hit, and global invalidate operations. A CAM-BIST (built-in self
test) is also available to test the function, timing, and critical
paths of the CAMTile. "ISSI believes that the patented CAMTile
technology can be very useful for those looking to embed a CAM into
their ASICs because of the CAMTile's flexibility, performance, and
enabling technology," said Nelson Chow, ISSI's Senior Director of
Network Search Products. As customer systems outgrow the need for a
smaller, embedded CAM, they can seamlessly transition into using
ISSI's standalone IS51VV4064 CAM-based 533 MSPS multi-search
processor, which uses the exact same technology and architecture
with which the customer is already familiar. Applications that have
table look-up functions include, but are not limited to: network
switches, routers, gateways, firewalls, intruder detection systems,
network concentrators, load balancers, storage network equipment,
web servers, graphic chips, and data compression chips. Packaging
