16-bit Digital Signal Processors

Tue, 07/31/2001 - 4:30am
Analog Devices revealed he new Blackfin™ family of 16-bit digital signal processors (DSPs) and the world's first product to integrate the high-performance Micro Signal Architecture jointly developed with Intel Corporation. Designed for telecommunications and a range of Internet appliances, this new Blackfin™ DSP shortens software and hardware development time through a programmer-friendly architecture and on-chip interfaces to ADI's data converters. To maximize the unique Dynamic Power Management features within the architecture, ADI also disclosed a companion power management chip that can precisely vary the voltage of the DSP. This unprecedented degree of control can reduce power consumption in Blackfin™ DSP-based designs by more than 60 percent.

The new Blackfin™ DSP operates at 300 MHz, delivering up to 600 million multiply accumulate instructions per second (MMACs) and power consumption as low as 42 milliwatts (mW) at 0.9 volts (V). The Blackfin™ DSP improves the performance of ADI's DSP portfolio by more than four fold and reduces the power consumption by almost one third. The Blackfin™ DSP family will extend to devices delivering up to 1 GHz performance.
