- Stac 9410 High-Speed Data
- Compression Chip 11/11/94 SAN DIEGO,
- CALIFORNIA, U.S.A. 1994 NOV 11 (NB) -
- - Stac Electronics (NASDAQ:STAC) has
- announced the Stac(a) 9410 V.42bis
- data compression accelerator. A
- leading supplier of compression
- products for data storage and
- communication, Stac recently won a
- patent dispute resulting in a 15
- percent equity investment by
- Microsoft.
-
- According to Robert Lutz, Stac's
- semiconductor product manager, the
- 9410 offers improved performance,
- reduced power consumption and reduced
- board area all at significant savings
- because it allows modem manufacturers
- to use 8-bit rather the more
- expensive 16-bit CPUs (central
- processing units).
-
- Today's modems typically use
- software on an internal CPU to
- implement data compression. That
- means less efficiency which can
- consume more than 80 percent of a
- modem's CPU overhead to perform the
- task of compressing and decompressing
- data, Lutz contends.
-
- The result, says Lutz, is while
- modem speeds have increased, the CPU
- has had to become more powerful to
- meet the needs of higher throughput
- and the increased
- compression/decompression
- requirements.
-
- Stac's 9410, akin to a co-
- processor for modem data compression,
- eliminates the speed bottleneck of
- compression, allowing a low cost 8-
- bit CPU to be used for high
- performance V.34 (28.8kb/s) modems.
-
- By incorporating Stac's new chip
- into their designs, modem
- manufacturers will realize
- performance benefits and cost
- reductions which can then be passed
- on to their customers, Lutz claims.
-
- Modems based on 8-bit CPUs may
- fall far short of the performance
- possible with 16-bit CPUs. However,
- modems based on more powerful 16-bit
- CPUs are considerably more
- expensive.
-
- Gary Clow, Stac's president and
- chief executive officer, told
- Newsbytes, "This chip will set a new
- standard of performance and price.
- Modem users will no longer have to
- sacrifice modem speed for low cost.
- Modems that don't use Stac's V.42bis
- accelerator will miss the market by
- either being too slow compared to the
- competition, or too expensive."
-
- Clow confirmed to Newsbytes that
- Stac is committed to offering data
- compression for PC telecommunications
- as well as operating systems.
- Additionally, the company will be
- offering full featured
- telecommunications remote control
- software. Clow expects these new
- offerings by the company to offset
- any sales lost by the licensing
- arrangement/settlement with
- Microsoft.
-
- For end users, the ability to get
- 16-bit performance with an 8-bit CPU
- means lower cost, and lower power
- consumption for longer battery life,
- he said.
-
- "8-bit modems simply can't keep
- up with the fast V.34 standard, and
- 16-bit modems have too high of a
- manufacturing cost," said Lutz. "But,
- an 8-bit modem with the 9410 reduces
- costs, and will outperform even a 16-
- bit modem. We are not talking about
- saving a few pennies here and there -
- - we are talking about reducing the
- modem manufacturing costs by several
- dollars."
-
- The 9410 is currently available
- in sample quantities. Full volume
- shipments are expected during the
- first quarter of 1995 and will be
- priced at about $7 in 100,000-unit
- quantities.
-
- Evaluation boards are available
- from Stac for Rockwell's L39, and
- Intel's 8051 and 80188 processors. A
- 9410 evaluation upgrade option is
- also available for Rockwell's WCEM
- modem evaluation platform.
