The ADSP-2183x/ADSP-SC83x digital signal processors (DSPs) are members of the SHARC®-FX family of products. The SHARC-FX core uses a single-instruction, multiple-data (SIMD) vector floating-point architecture and can issue up to four instructions per cycle in most combinations. The SHARC-FX core inside the ADSP-2183x/ADSP-SC83x processors offers processing speeds of up to 1 GHz coupled with up to 2 MB of L2 memory for low latency applications. For applications seeking enhanced connectivity options such as Ethernet, the ADSP-SC834/SC835 includes an Arm® Cortex®-M33 in addition to the SHARC-FX core. All members of the SHARC-FX family have on-board IIR and FIR accelerators as well as an efficient auto-vectorizing compiler for C/C++ programming.
The SHARC-FX core supports scalar and vector operations on all data types in vectors up to 256 bits, including integer, fixed-point, floating-point, complex 16-bit/32-bit fixed-point and complex 32-bit/64-bit floating-point. Eight float32 multiply/accumulate operations are allowed per cycle, with no constraints on alignment. The SHARC-FX core also features large register sets (32 data registers), thus reducing the need for stack save and restore. The peripherals and system architecture of the ADSP-2183x/ADSP-SC83x processors are compatible with previous SHARC processors, allowing for easy application porting.
By integrating a set of industry-leading system peripherals and memory, this family of processors is the platform of choice for applications that require 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 for head units and amplifiers, ANC/RNC, digital cockpit, ICC, AEC/Mic beamforming, ADAS
- Consumer:
- speakers, sound bars, AVRs, conferencing systems, mixing consoles, microphone arrays

Product Detail
The ADSPSC835W-EV-SOM enables evaluation and rapid prototyping of designs featuring the ADSP-SC83x/2183x Family (ADSP-SC834/ADSP-SC835/ADSP-21836/ADSP-21837) of SHARC-FX 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 ADSP21835-EV-SOM board is plugged into the EV-SOMCRR-EZKIT or 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 ADSP21835-EV-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 ADSP21835-EV-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
- Read and write core and peripheral registers
