LSI Logic announces ZSP Digital Signal Processor Core Module boards for ARM+DSP solution

• Modules speed development time of ARM+DSP technology-based SoC and platform designs
• Open-architecture ZSP Processor Core Module boards provide ability to rapidly prototype complex DSP functions in an ARM Integrator environment
• LSI Logic's popular ZSP400 and ZSP500 DSP cores support tight integration with ARM processors for bus, interrupt and debug facilities

MILPITAS, Calif., Oct. 15, 2003 - LSI Logic Corporation (NYSE: LSI) today announced the availability of two ZSP® Processor Core Module boards, the EB500P_CM and EB400P_CM (http://www.zsp.com/products/core_modules.html). For SoC and platform developers interested in integrating a high performance ZSP500 or ZSP400 processor subsystem with any available ARM® processor core module, these comprehensive solutions provide for seamless integration and a rapid prototyping environment for shortened time-to-market.

"LSI Logic has developed a proven integration approach to the ARM processor and provides a differentiation capability for customizing the DSP subsystem to target voice, multimedia or wireless applications," said Steven Brightfield, business development manager, LSI Logic DSP Products Division. "This seamless integration and product prototyping of ARM cores plus ZSP-based multi-core processor SoC designs, forms the foundation for a series of complete DSP processor subsystems under development at LSI Logic in conjunction with our solution partners."

The EB500P_CM board features an entire silicon subsystem implementation of the ZSP500 processor, including memory controller; 512 Kbytes of SRAM; JTAG controller; embedded trace; clock controller; co-processor interfaces; master/slave AMBA™ AHB bus interface and associated logic. The EB400P_CM board features a native implementation of the ZSP400 processor with memory controller and processor interfaces accessible in FPGA logic. The boards each contain an FPGA that provides a local AHB bus, a bridge to the global system AHB bus, and board-specific peripherals such as serial ports and LCD drivers. Customers can add their own logic to the FPGA to incorporate their specific functions in RTL coupled with the processors.

"As SoC designs continue to increase in size and complexity, verification becomes increasingly time-consuming," said Matthew Byatt, marketing manager, ARM. "With its ZSP Processor Core Module boards, LSI Logic is reducing the risk, cost and complexity of integration by providing the ability to rapidly prototype complex DSP functions in an ARM Integrator environment."

Support for AMBA Methodology
The ZSP500 silicon features a complete AMBA AHB pinned-out interface that interconnects to the Core Module board's FPGA to provide flexible subsystem development options. The FPGA can incorporate a variety of customer developed, loosely or tightly coupled hardware accelerators, peripherals, additional memory and/or DMA controllers. The FPGA also facilitates interconnection to the ARM Integrator Platform (http://www.arm.com/devtools/Integrator_AP?OpenDocument) board via the AHB bus for signaling to other processors or peripherals in the Integrator system. This provides for a seamless interface to platform level IP integrations of a ZSP core and a large variety of ARM microprocessor hosts.

Multi-core Debug and Development Tools
With best-in-class debugging features, the LSI Logic ZSP Core Module boards offer multi-core debug using either Green Hills™ Multi™ 2000 or the ARM RealView™ Developer Suite. These products enable simultaneous debugging of both cores with a common debugger. The boards can also be used with independent debuggers rather than a single one. JTAG probes from a number of Solution Partners including Green Hills and First Silicon Solutions are also available to communicate with the boards.
