SHARC 2148x, 2147x DSPs

Analog Devices Inc. rolls out 32bit floating-point DSPs with up to 5Mb on-chip memory that extends signal processing precision to a wider range of apps and enable high-end system functionality in portable devices. The SHARC 2148x and SHARC 2147x series is an extension to its range of 32bit floating-point DSPs.

Designers can also take advantage of end-to-end SHARC family code compatibility and a suite of ADI development tools.

The SHARC 2148x series processors deliver 400MHz performance and up to 5Mbit on-chip memory making them suitable for high-definition audio and home theatre applications, as well as advanced industrial applications.

The SHARC 2147x series with typical power consumption 363mW are suitable for portable devices and applications like advanced driver assistance systems (ADAS) that require floating-point processing precision with low power consumption and high environmental tolerance. The devices measure 12mm x 12mm and deliver performance up to 266MHz.

Both the 2148x and 2147x processors feature dedicated hardware accelerators with independent compute units and DMA memory mapping, enabling the ability to execute FFT/FIR/IIR signal processing operations in the background to free up MIPS for core processing.

Memory usage is optimised via Variable Instruction Set Architecture support, which can free up as much as 30 per cent of memory space for application code through reductions in instruction opcode sizing. The thermal diode, available in 100-ld LQF packages only enables high-ambient temperature operation.

With integrated audio-centric peripherals and dedicated on-chip decoders to enable high-performance audio product designs, SHARC 2148x processors provide algorithm processing that can now be applied to consumer audio/video receivers systems requiring low-cost, single-chip board implementations.

In addition, the SHARC 2147x processors provide the computational precision to facilitate RADAR-based ADAS including adaptive cruise control, blind spot detection and cross traffic alert, enabling optimal target resolution, multi-target tracking and real-time system responsiveness for safety-critical applications.

The SHARC 2147x processors are also optimised for portable medical devices providing precise signal processing to yield accurate patient data that healthcare professionals can count on to expedite treatment decisions.

Third-parties providing value-added design services and technology for the SHARC 2148x and SHARC 2147x series include AeVee Labs, Danville Signal Processing, DSP Concepts, Kaztek Systems and the MathWorks.
