****ot Lucent Introduces Wireless Base Station DSP With 50
Percent Better Performance Than Competing Products Chip Consumes
One-Fifth The Power, Is One-Third The Size Of Nearest Competitor
CANNES, France, Feb. 23 /PRNewswire/ -- Lucent Technologies Microelectronics Group today introduced a digital signal
processor (DSP) chip that performs more than 50 percent better than all wireless base station chips.
Lucent's DSP16410* performs up to 800 million multiply and accumulate operations per second (MMACS) -- more than a 50
percent performance improvement over the chip's nearest competitor. The chip also consumes up to five times less power (.38
watts) and is less than one-third the size (15 by 15 millimeters) of the nearest competing chip. These features help to
dramatically lower component and system costs of base stations while increasing overall performance and versatility.
Lucent's chip, the latest version of the company's DSP16000 product family, is being introduced today at the GSM World
Congress in Cannes, France (Feb. 23-25, Booth A12).
''Lucent's new chip is further evidence why the company is the world's number one provider of DSPs for wireless base
stations,'' said Will Strauss, president of Forward Concepts, a DSP market research firm based in Tempe, Arizona. ''The
DSP16410 proves that Lucent is heavily committed to providing higher-performance, lower-power, and more compact
solutions using its well-regarded DSP16000 architecture. Couple this broadening of the DSP16000 product portfolio with the
company's focused and multi-faceted DSP initiative involving Star*Core**, and Lucent clearly is attacking the communications
DSP market on several different fronts.''
The DSP16410 can process greater than three-and-a-half more voice channels in the same amount of circuit board area as the
nearest competing chip. As a result, base station manufacturers can fit more DSPs on the same size circuit board or develop
smaller boards and use fewer DSPs. Both benefits help lower costs and increase versatility of base station components and
systems without sacrificing processing power.
The DSP16410 includes two DSP16000 cores. The chip houses more than 3 megabits (388 kilobytes) of Random Access
Memory -- a large amount for base station DSP devices -- that enables more flexibility in the amount and types of DSP
programming available using this chip. A centralized direct memory access (DMA) controller off-loads memory-to-memory
and memory-to-peripheral transfers, thereby increasing the chip's processing efficiency. Higher-bandwidth enhanced on-chip
interfaces have also been included, enabling the chip to process data, which is becoming a requirement for 3G wireless
infrastructure systems.
''Having two DSP cores on the DSP16410 is like having two high-powered engines on one chip,'' said Aaron Fisher, vice
president of the wireless business unit with Lucent's Microelectronics Group. ''That extra horsepower now means more DSP
speech coders can fit on one chip -- for example 29 Enhanced Full Rate speech coders -- which translates to the need for
fewer DSPs, thereby lowering costs. We continue to emphasize minimizing power and size of DSPs while increasing
performance as the key to satisfying our customers.''
The DSP16410 can be used in all wireless voice and data standards including third-generation Wideband Code Division
Multiple Access (CDMA), Narrowband CDMA, Global System for Mobile Communications (GSM), and Time Division
Multiple Access (TDMA).
The company's DSP16410 product is scheduled to be available in sample quantities in this year's second quarter and in volume
quantities in this year's fourth quarter. The chip, which will be priced at $80 in quantities of 10,000, is expected to be
manufactured in production quantities using Lucent's .16 micron process technology.
The wireless base station DSP market amounted to approximately $160 million in 1998, according to Forward Concepts. The
market is projected to grow at a 20 percent compound annual growth rate to reach approximately $410 million by the year
2003.
