Product lowers third-generation-device-development costs

Using Analog Devices' ADSP-TS101S DSP to develop third-generation base-station systems costs significantly less than using a DSP for symbol-rate processing or using ASICs and FPGA implementations for chip-rate processing. The TS101S includes instructions for chip- and symbol-rate processing that supports an all-software approach, eliminating the need and cost for ASICs or FPGAs and separate memories for chip- and symbol-rate processing. A software implementation simplifies migrating between evolving and major third-generation modes, such as wide-bandwidth CDMA/UMTS, cdma2000 and TDS-CDMA. The TS101S comes in a 19×19-mm PBGA package, dissipates less than 1W, and requires no heat sinks or forced-air cooling.

The TS101S is available now for less than $100 (25,000). Analog Devices' VisualDSP++ development suite includes a compiler, an assembler, a linker, a simulator, a debugger, the VDK RTOS kernel, and an in-circuit emulator to support development for the TS101S. Layer 1 modules are available for wide-bandwidth CDMA, cdma2000, and TDS-CDMA, and a spreadsheet tool lets you analyze system-resource requirements for third-generation functions. Ibis models, electrical-performance data, and link-port Verilog/VHDL models are also available.
