Analog Device's New Low Cost SHARC DSP Delivers Breakthrough System Integration and Performance
Industry's leading multiprocessing DSP platform offers code-compatible road map from $5 to 10GFLOPS
NORWOOD, Mass., Sept. 5 /PRNewswire/ -- Analog Devices, Inc. (NYSE: ADI - news) announced today the ADSP-21161 SHARC® DSP, the newest member of the Super Harvard Architecture (SHARC) family of programmable digital signal processors (DSPs). Capable of 600 million math operations per second (MFLOPs), the ADSP- 21161 sets a new level of performance for low-cost SHARC DSPs - more than three times the performance for comparable models at about the same price. System integration has been optimized for applications such as voice recognition, professional and high-end consumer audio, motor control, automotive entertainment, telephony including mobile telephony, instrumentation, network analysis, network infrastructure and wireless communications. These applications will benefit from the integration of one megabit of memory and ADI's industry-leading multiprocessor interfacing technology.

``The ease-of-use of 32-bit, floating-point DSPs is a tremendous benefit to designers, improving their time to market. A broad portfolio of SHARC DSPs brings these ease-of-use advantages to a wide range of real-time signal processing and multiprocessing applications,'' said Gerald McGuire, product line director, Digital Signal Processing Division, Analog Devices. ``Our road map includes a cost-effective path to 1200 MFLOPS for $5 per unit and a performance-driven path to 10GFLOPS and beyond.
This announcement builds on the continued success of the SHARC family of DSPs. In 1998 Analog Devices was the first major manufacturer to create successful solutions for the low cost, floating-point segment of the of DSP market with a product that was twice as fast as any 32-bit DSP available on the market at the time and more than three times faster than any 32-bit DSP in its price range. This new ADSP-21161 redefines the floating-point market with a further threefold increase in performance, a rich peripheral set and high bandwidth communications. In addition, this announcement will enable designers to quickly and easily build code-compatible, cost-effective, scaleable, single and multiprocessor solutions. Both segments of the SHARC family road map will offer products with a variety of price points, memory sizes and peripherals.
``This newest edition to the SHARC family will open more possibilities for designers to design-in high performance digital signal processing into client- side applications, and should help others reconsider applications they couldn't do before with a single chip,'' said Will Strauss, president of Forward Concepts. ``Analog Devices will certainly maintain customer loyalty with this road map,''
The ADSP-21161 - Breakthrough in System Integration
The ADSP-21161 is based on the SIMD SHARC core that supports single- instruction, multiple data execution of 32-bit fixed and floating point arithmetic. It has 1Mbit of on-chip dual-ported memory. This dual ported SRAM has a unique feature that permits the user to customize the mix between the percentage of memory dedicated to instruction and the percentage of memory dedicated to data consistent with the demands of the specific application. The result is a more efficient use of memory and processing power. Fourteen direct memory access (DMA) channels assure fast data transfers that do not steal cycles from the core. System I/O is achieved through two 128-channel synchronous TDM and four I2S serial ports, a 32-bit parallel port that includes a 32-bit SDRAM controller and an SPI interface. Clusters of DSPs can be built using the on-chip multiprocessing interfaces which enable global shared memory within the cluster, and connection of up to six SHARC DSPs and a host without the need to design external circuitry. It also provides hardware and software compatibility with over 70 multiprocessing design tools available from third parties. The 3.3 volt device is 5.0 volt-tolerant for I/O.
Tools Support
A wide range of software and hardware development tools supports the ADSP- 21161 and subsequent SHARC DSP products. Analog Devices' VisualDSP®++ development tools include an optimizing C/C++ compiler, easy-to-use hardware evaluation kits, and in-circuit emulators (ICEs). SHARC emulators provide easier and more cost-effective methods for engineers to develop and optimize SHARC systems, by offering non-intrusive full speed emulation capabilities.
Price and Availability
The ADSP-21161 is manufactured with a state-of-the-art .18 micro CMOS process.
Entry price for the 100 MHz ADSP-21161NKB-100X, 225-BGA (ball grid array) is $35/unit in 1,000 unit volumes. Sampling is planned for Q4, 2000 with full production in mid-2001.
