ADSP-SC59x/2159x SHARC Series Doubles Portfolio Performance, Enabling Platforms for Complex Audio Applications

  • ADSP-2159x Offers Pin-Compatibility with ADSP-2156x Processors, Providing DSP Performance Scalability from 400 MHz to 2 GHz
  • Leverages SHARC+ Cores and Advanced Filter Accelerators to Provide >3-7x the Device Performance of Prior Generations

The ADSP-SC59x (ADSP-SC598 / SC596 / SC594 / SC592) and ADSP-2159x (ADSP-21594 / 21593) series of processors are designed to provide immersive audio and sound experience in automotive and consumer/pro-audio applications. The ADSP-SC59x/2159x audio processors are specifically targeted for applications that demand deterministic and low-latency real-time audio processing, including immersive 3D sound and personal audio zones, automotive active and road noise cancellation (ANC/RNC), voice-based user-interfaces and in-car communications (AEC/NR & microphone beamforming), and engine sound synthesis (ESS) and electric vehicle warning sound systems (EVWSS/AVAS). Additional applications include professional audio and soundbars / home AVRs (with 3D Object and Multi-Channel Audio).

DSP Concepts

Analog Devices has partnered with DSP Concepts to optimize the Audio Weaver® core libraries specifically for the SHARC+® DSP core, leveraging the high-performance on-chip FIR/IIR hardware accelerators wherever possible, resulting in even more processing power. Audio Weaver contains tools that facilitate development from prototype to production. It is a low-code audio platform that streamlines automotive audio development and reduces risk and complexity by utilizing a drag-and-drop host application for product design, paired with an audio processing engine embedded in the DSP. Leveraging an 4-in/12-out audio flow developed by DSP Concepts using Audio Weaver, the ADI LISTN™ EZ-Audio System provides a turnkey integrated audio solution that can be tuned to any automotive cabin.

The ADSP-SC59x/2159x family are single- or dual-SHARC+ DSP core floating-point processors, combining flexible audio connectivity and performance scalability across a number of pin-compatible products with several on-chip memory options. As they are software- and pin-compatible with the ADSP-21566 / 21567 / 21569 audio processors, the ADSP-21593 offers DSP performance scalability from 400 MHz to 2 GHz. Meanwhile, the ADSP-SC594 / SC592 processors integrate an Arm® Cortex®-A5 (1800 DMIPS at 1 GHz), while the ADSP-SC598 / SC596 processors integrate an Arm Cortex-A55 (3400 DMIPS at 1.2 GHz), both with FPU and Neon® DSP extensions, providing a control processor for enhanced integrated peripherals including Gigabit Ethernet (w/AVB), 3-pin and 6-pin MLB, USB, and CAN-FD.

ADI’s software development tools enable solution developers to achieve fast time to market. Optimized software-based audio algorithms can be tuned for specific use cases for ease of solution design and reduced development effort.

The ADSP-SC59x/2159x processors are available in a 400-ball FCBGA (17mm x 17mm, 0.8mm pitch) package in both automotive and consumer grades to provide design flexibility and enable thermally efficient compact designs across operating temperature range.
