LSI Logic Expands ZSP(TM) Portfolio With Cost-Effective, Configurable DSP Standard Product
MILPITAS, Calif., Aug. 28 /PRNewswire-FirstCall/ --
LSI Logic Corporation (NYSE: LSI) today announced the addition of a new
low-power, configurable digital signal processor (DSP) to expand its ZSP(TM)
DSP standard product portfolio. Based on LSI Logic's ZSP?400 core, the
LSI403LP is designed for cost-sensitive applications requiring low power
consumption, high throughput and flexibility such as consumer electronics and
customer premise equipment (CPE). These applications, which include such
equipment as digital audio players, cable and DSL modems and set-top boxes,
require advanced signal processing technology to support high quality audio
and voice services. A key competitive advantage of ZSP standard products is
the ability for customers to later migrate to system-on-chip integration for
further cost reduction, while leveraging their software investment. ZSP
technology is the only DSP solution in the market available in all three
forms: standard product, ASIC core and licensable IP.
"DSPs are permeating the consumer electronics market at lightning speed,"
said Will Strauss, president of market research firm Forward Concepts. "The
introduction of the LSI403LP by LSI Logic clearly serves the needs of this
market with a cost-effective DSP with performance and flexibility to address
its ever increasing need for signal processing capabilities."
The cost-effective 16-bit fixed-point LSI403LP is LSI Logic's first DSP to
be implemented in a 0.13 micron copper technology process, resulting in a
smaller die size and power consumption reduction. The LSI403LP with flexible,
on-chip memory consists of 16K words of instruction memory, 16K words of data
memory plus 16K words of configurable on-chip instruction/data memory.
Configurable memory allows developers to optimize on-chip instruction and data
memory allocation for their specific applications. The total of 48K words of
on-chip memory can support complete audio and voice applications, eliminating
the need for external memory that would increase system cost and power.
"This latest addition to our ZSP standard product portfolio offers an
attractive combination of price, performance and configurability that hits a
sweet spot for DSP applications," said Tuan Dao, vice president of LSI Logic's
DSP Division. "Combined with available production ZSP software for
industry-standard algorithms, system designers can benefit immediately from
the LSI403LP device."
Features, Benefits and Availability
The LSI403LP is housed in a 208-pin PQFP package and operates up to
150 MHz for a maximum throughput of 600 million instructions per second
(MIPS). This is achieved via a four way superscalar engine with four
execution units; two multiply accumulate units (MACs) and two arithmetic logic
units (ALUs). This functionality allows the LSI403LP to execute two
multiply-accumulate operations in a single clock cycle deliver
high-performance while consuming less than 0.12mW/MIPS of power in a typical
application. In addition, single cycle 32x32-bit multiply, bit-manipulation
and 32-bit arithmetic and logic operations are supported for optimal
performance that addresses the dynamic range requirements of audio processing
applications. For maximum I/O performance and flexibility, the LSI403LP
provides two high-speed time-division multiplexing (TDM) serial ports with
integrated G.711 PCM companding hardware, a single 8-bit host processor
interface (HPI), and external memory interface unit, and 4-pin programmable
I/O (PIO) port. Other on-chip peripherals include two 16-bit timers and an
enhanced 8-channel DMA controller. Documentation for the LSI403LP device is
available at http://www.zsp.com/lsi403lp.html .
The LSI403LP is sampling now and will be in production in Q4 2002. The
device is priced well below $10 in volume shipments.
About LSI Logic's ZSP Family of DSP Cores
LSI Logic's ZSP superscalar signal processing technology provides the
highest performance open architecture DSP cores available today. These
licensable and fully synthesizable cores have been successfully implemented in
ASICs and standard products alike. The ZSP architectures have been optimized
with respect to code density, compiler performance and ease of programming. A
key advantage of the ZSP technology is that it maintains code compatibility
between core families, enabling users to address applications ranging from
low-power, portable devices to high-density gateways, while preserving their
investment in code development. ZSP technology is supported by the
standardized ZOpen(TM) application development framework and a growing list of
third party Solution Partners. For more information about the ZSP visit the
