SHARC Audio Processors/SoCs

Featuring the Analog Devices SHARC® and SHARC+® digital signal processing (DSP) core technologies, the SHARC audio processor portfolio offers deterministic and very low processing latency with best-in-class MIPS/mW performance. The SHARC processor family dominates the floating-point DSP market with exceptional core and memory performance and outstanding I/O throughput. With multiple product variants and price points, SHARC brings real-time floating-point processing performance to many applications where dynamic range is key.

Many processors feature FIR/IIR hardware accelerators to offload common digital signal processing algorithms from the core, thus freeing the core to perform post-processing algorithms in parallel, making them the ideal choice for real-time audio applications. The broad SHARC+ SoC portfolio provides performance scalability up to 1GHz and a variety of on-chip memory configurations and peripheral mixes. For complex peripherals such as Ethernet and USB, some SoCs feature an integrated ARM core to handle running stack software and other microcontroller tasks.
