LSI Logic Unveils Highly Efficient Quad-MAC DSP Core Targeting Advanced Mobile Multimedia Applications

• The ZSP540 provides improved performance with power/size efficiencies of a dual-MAC DSP
• LSI Logic offers most comprehensive family of software compatible DSP cores in the industry

MILPITAS, Calif., Oct. 6 /PRNewswire-FirstCall/ -- LSI Logic Corporation (NYSE: LSI) today announced immediate availability of the highly efficient ZSP540 digital signal processor (DSP) core. The ZSP540 core is a quad-MAC/six-ALU implementation that can run up to five instructions per cycle, combining the benefits of the dual-MAC ZSP500 core with the ultra performance quad-MAC ZSP600 core. The ZSP540 core is ideally suited to meet the demands of multi-channel voice processing, 3G baseband processing, media-rich applications and other applications requiring additional parallel DSP compute performance.

The ZSP540 augments the existing ZSP(R) core roadmap to be the most comprehensive offering of licensable, software compatible DSP cores. SoC designers can choose the most suitable ZSP core for their application without compromising scalability or their software investment. The ZSP540, like all other ZSP cores, can run software previously written for another ZSP core, providing a scalable path for core selection with maximum design reusability.

Will Strauss, president of market research firm Forward Concepts in Tempe, Arizona and leading analyst for the DSP marketplace, commented: "LSI Logic has continued to expand its ZSP portfolio of DSP cores. Now, with the introduction of the ZSP540, the ZSP technology addresses the 3G wireless handset market while extending its reach into new applications like image processing, advance navigation systems and other areas requiring higher bandwidth and advanced complex-arithmetic performance."

Based on the G2 architecture, the ZSP540 leverages world-class software development tool chains, SoC design tools and comprehensive suites of readily available software for voice processing, audio/video multimedia applications and more. The ZSP540 is also equipped with the Z.Turbo(TM) accelerator feature allowing SoC designers to further accelerate the processor performance through instruction set extension or coprocessor implementation.

"With its quad-MAC capabilities at the system cost of a dual-MAC core, the ZSP540 delivers a new 'sweet-spot' in price, power and performance," said Tuan Dao, vice president and general manager of the LSI Logic DSP Division. "The advanced performance, low power consumption and higher code density of the ZSP540 make it very appealing for customers providing feature-rich multimedia 3G wireless solutions."
