Launch of the latest SHARC® processor platform
Announcement of additional ADSP-SC57x and ADSP-2157x processors

Analog Devices (CEO Jaehoon Yang) announced the ADSP-SC57x and ADSP-2157x processors, which belong to the single-chip multicore SHARC® processor family.

The newly announced processors enable the construction of audio systems with excellent sound quality, cost-effectiveness, and stability, delivering a better audio experience to users. The new processor platform can meet automotive temperature ranges without the need for large and expensive heat sinks or fans, saving space in end applications.

This product family combines ADI’s SHARC technology with ARM® Cortex-A5 system control capabilities to provide a high-performance, low-cost solution for complex applications such as Dolby Atmos®, DTS:X®, or active noise cancellation, with ample performance headroom reserved for additional audio post-processing.



Target applications include high-end automotive audio, consumer and professional audio, and industrial systems that require excellent floating-point performance. With over 2MB of on-chip memory built-in, designers can achieve higher DSP performance with lower power while reducing system complexity, time-to-market, board space, and cost.

The SHARC+ core and DSP accelerator use ADSP-SC57x processors to provide real-time performance, while ARM® Cortex-A5 processors handle connectivity and system operations. The ARM® NEON™ engine can be used to add signal processing capability if needed.

These features are combined with the latest interface technologies, including Gigabit Ethernet AVB, MLB for MOST150, CAN 2.0B, USB 2.0, and mobile storage, all of which are managed independently by ARM processors and provide optimized flexibility when designing systems from a common family.

The ADSP-SC57x processor offers scalable performance by providing a choice of two packages utilizing ARM and single or dual SHARC+ DSPs. In addition to large-capacity on-chip memory, these two package options allow for the selection of whether to use external DDR3(L)/DDR2/LPDDR1. This option enables designers to optimize both BOM costs and board complexity. The ADSP-2157x family is designed for applications requiring only a DSP.

This product family includes two SHARC+ cores, a DSP-centric peripheral set, and a computational accelerator. As the demand for increasingly complex audio algorithms in automotive and consumer applications, such as multi-channel audio decoding and active noise cancellation, grows, requirements are becoming increasingly stringent; however, the outstanding DSP performance of this product family can satisfy these demanding requirements.

The new processor includes ARM® TrustZone® security, an integrated cryptographic hardware accelerator, and secure OTP memory for key storage to alleviate growing industry concerns regarding software IP protection.
