Reaching speeds of up to 933 MHz, the ADSP-21568 processors are members of the SHARC® family of products. These processors offer a cost-reduced pin- and code-compatible option to the ADSP-21566/ADSP-21567/ADSP-21569 processors, while offering double the L2 memory (2MB) and supporting the peripheral functions of the ADSP-21562/ADSP-21563/ADSP-21565 LQFP package products.
The processors are members of the SIMD SHARC family of digital signal processors (DSPs) that feature Analog Devices, Inc., Super Harvard Architecture. These 32-bit/40-bit/64-bit floating-point processors are optimized for high performance audio/floating-point applications with large on-chip static random-access memory (SRAM), multiple internal buses that eliminate input/output (I/O) bottlenecks, and innovative digital audio interfaces (DAI). Additions to the SHARC+ core include cache enhancements and branch prediction, while maintaining instruction set compatibility to previous SHARC products.
By integrating a rich set of industry-leading system peripherals and memory, the SHARC+ processor is the platform of choice for applications that require programmability similar to reduced instruction set computing (RISC), multimedia support, and leading edge signal processing in one integrated package. These applications span a wide array of markets, including automotive, professional audio, and industrial-based applications that require high floating-point performance.
APPLICATIONS
- Automotive:
- audio amplifier, head unit, ANC/RNC, rear seat entertainment, digital cockpit, ADAS
- Consumer & Professional Audio:
- speakers, sound bars, AVRs, conferencing systems, mixing consoles, microphone arrays, headphones

Product Detail
The EV-21568-SOM enables evaluation and rapid prototyping of designs featuring the ADSP-2156x Family (ADSP-21560/ADSP-21561/ADSP-21564/ADSP-21568) of SHARC+ audio processors. It provides an easy-to-use plug-n-play reference design with expansion capabilities to interface to custom hardware ahead of the release of the processor itself. When the EV-21568-SOM board is plugged into the EV-SOMCRR-EZLITE carrier board, the resulting EZ-KIT® evaluation system can be used for fast and easy evaluation of the processor core and system peripherals/interfaces.
The EV-21568-SOM enables rapid prototyping for a wide range of applications, including immersive 3D sound and personal audio zones (PAZ), automotive active and road noise cancellation (ANC/RNC), voice-based user-interfaces and in-car communications (ICC), 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) and enhanced conferencing systems. ADI offers several software modules (e.g., AEC/NR, microphone beamforming, pitch shifting, harmonic generators, wave players, etc.), as well as complete software solutions that can be licensed, where users can develop/evaluate their audio and voice processing applications. ADI also offers 3rd party surround sound solutions that can be licensed on ADI’s SHARC processor families. Please visit ADI’s Software Solutions page for more information.
The EV-21568-SOM module utilizes the CrossCore® Embedded Studio (CCES) development tools to enable developers to achieve faster time to market. The development environment aids advanced application code development and debug, such as:
- Create, compile, assemble, and link application programs written in C++, C, and assembly
- Load, run, step, halt, and set breakpoints in application programs
- Read and write data and program memory <li<></li<>
