Infineon introduces configurable CARMEL DSP Core for 3G wireless and broadband communication applications

Mar 27, 2000 | Market News

Munich/Germany – March 27, 2000 – As a major step in reinforcing its position in 3G (third generation) wireless and broadband connectivity products, Infineon Technologies today announced the second generation 16-bit, fixed-point CARMEL™ DSP core. The 20xx core features PowerPlug™ accelerators that enable SoC developers to configure the instruction set as well as to modify the core. As a result the PowerPlug™ accelerator can implement computation-intensive features such as multiple data rates and complex modulation schemes without compromising power dissipation and system costs.

With Infineon’s PowerPlug™ modules, system designers can accelerate the execution of application-specific functions to boost DSP performance by reconfiguring the DSP core. The PowerPlug™ modules are tightly coupled to the CARMEL™ DSP core and are viewed by the software as built-in execution units of the DSP datapath. Their addition results in scalability across hardware and software and optimization of cost and performance.

“The PowerPlug™ technology combines the price/performance benefits of ASIC design with the flexibility of a programmable DSP,” said Shaul Berger, vice president of Infineon Technologies’ DSP Cores. “CARMEL™ DSP 20xx core’s scalable architecture allows our customers to offer cost-competitive 3G wireless and broadband products faster to market.”

The core’s instruction set is a superset of the first generation CARMEL™ DSP 10xx core, featuring the CLIW™ (Configurable Long Instruction Word) architecture. The CLIW™ technology combines the benefits of the VLIW’s high performance and flexible control and SIMD’s (Single Instruction Multiple Data) compact code and low power, without the associated penalty in code size and power dissipation usually found in VLIW architectures.

The CARMEL™ DSP 20xx core initially provides for frequencies up to 300 MHz. Through the PowerPlug™ extensions, the new core’s code-efficient DSP MIPS can double the performance of the native core without compromising power dissipation. The additional processing power made available by the PowerPlug™ technology meets the requirements for faster data transfer rates and the convergence of voice, data and video over wireless and broadband applications. The CARMEL™ DSP 20xx core features energy-efficient DSP MIPS to extend battery life and support memory power saving mechanisms, enabling new mobile applications users to take advantage of 3G services.

The CARMEL™ DSP 20xx core will be available in the fourth quarter 2000.
