Analog Devices recently unveiled the newest additions to its SHARC portfolio of 32-bit floating point digital signal processors – the SHARC 2148x and SHARC 2147x series. Delivering up to 5 Mb of integrated memory, high performance SHARC 2148x and low power SHARC 2147x series processors extend single-chip, floating point signal processing precision to a wide range of applications and enable high-end system functionality in portable devices.
The new processors feature dedicated hardware accelerators with independent compute units and DMA memory mapping, with 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 (VISA) support, which can free up as much as 30% of memory space for application code through reductions in instruction opcode sizing.
With integrated audio-centric peripherals and dedicated on-chip decoders to enable high-performance audio product designs, SHARC 2148x processors enable designers to develop feature-rich HD audio and home theatre systems in increasingly smaller form factors. These processors equip designers with the performance, processing precision and peripherals to develop motor drive and industrial control systems. Designers can utilise visual development software to implement sophisticated algorithms that yield dynamic system control and energy efficiency.
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, multitarget tracking and real-time system responsiveness for safety-critical applications. With low power attributes and 105°C ambient operating temperature tolerance, SHARC 2147x processors meet automotive environment requirements. They are also suitable for portable medical devices that equip healthcare professionals with sophisticated diagnostic capabilities in clinics, emergency vehicles and other non-hospital settings.
