ADSP-2156x SHARC Product Family Delivers Lowest Latency, Highly Deterministic Real-Time Audio Processing Performance

Reaching speeds of up to 1 GHz, the ADSP-2156x processors are members of the SHARC^® family of products. The ADSP-2156x processor is based on the SHARC+^® single core. The ADSP-2156x SHARC 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). New 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 (see Table 1 in the data sheet), 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

CrossCore Embedded Studio is a world-class integrated development environment (IDE) for the Analog Devices Blackfin^®, SHARC^® and Arm^® processor families. Employing the latest generation of our mature code generations tools, this Eclipse^™ based IDE provides seamless, intuitive C/C++ and assembly language editing, code-gen, and debug support.

CrossCore Embedded Studio also offers Blackfin and SHARC developers highly integrated add-in support for drivers, services, and algorithmic software modules. These include driver support for on chip and off chip peripherals, stacks for Ethernet and USB, a popular real time operating system and file system, and more. It provides an easy to use development framework which includes exceptional integrated multicore development and debug support.

FreeRTOS is a free, scalable real-time operating system. This product supports for the Analog Devices ADSP-BF7xx, ADSP-215xx and ADSP-SC5xx (ARM Cortex-A5, ARM Cortex-A55 and SHARC+ cores) processor families.

FreeRTOS is a low memory operating system developed for embedded systems. It supports many common operating system concepts such as timers, events, mutexes, semaphores tasks and semaphores; all of which can be created dynamically or statically. It has a scheduler which can be configured to be preemptive or co-operative, with optional time slicing.

The EV-21569-SOM with low-cost evaluation and rapid prototyping of the ADSP-2156× Family (ADSP-21562/21563/21565/21566/21567/21569) of SHARC+ audio processors. It features the processor, memory, and power portions of the design and provides an easy-to-use plug-n-play reference design with all the key interfaces made available on three connectors for marrying to carrier board (EV-SOMCRR-EZKIT, EV-SOMCRR-EZLITE, or a custom board).

The EV-21569-SOM module requires 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

When used without an ADI carrier board, the EV-21569-SOM board requires an external in-circuit emulator (ICE-1000 or ICE-2000) be connected to the JTAG header.

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
