第四代SHARC®处理器系列, 现在包括ADSP-21486, ADSP-21487,ADSP-21489具有更高的性能，提供硬件型滤波器加速器、音频和应用专用外设，其新型存储器配置可支持最新环绕声解码器算法。所有器件均相互引脚兼容，且与以前的所有SHARC处理器全代码兼容。第四代SHARC处理器系列的这些最新成员基于一款单指令多数据(SIMD)内核制成，支持32位定点和32/40位浮点算法格式，是高性能音频应用的理想选择。
ADSP-21487提供最高性能——400 MHz/2400 MFLOP——采用LQFP封装，是第四代SHARC处理器系列中的一员。这一性能水平使ADSP-21487成为消费音频应用的理想之选。ADSP-21487不但拥有较高的内核性能，而且内置了FIR、IIR和FFT加速器等额外的处理模块，可以大幅提升系统的整体性能。可变指令集架构(VISA)是其特色新功能之一，可使代码减少20%至30%，从而提高存储器的可用性。第四代DSP为16位宽SDR SDRAM提供了一个无缝接口，可以连接外部存储器。
The EZ-KIT Lite includes an ADSP-21489 SHARC Processor desktop evaluation board along with an evaluation suite of the VisualDSP++® development and debugging environment, including the C/C++ compiler, assembler, and linker. The evaluation suite of VisualDSP++ is designed to be used with the EZ-KIT Lite only.
The EZ-KIT Lite also comes with a standalone debug agent board that is removable to allow a user to plug-in an external emulator.

The EVAL-MELODY-5 is a comprehensive, integrated DSP and HDMI™ based development platform to facilitate the design and development of AVRs, soundbars, multichannel gaming headphones and powered speakers. The hardware incorporates latest DSP and HDMI products and is supported by CrossCore® Eclipse-based tools and the user friendly GUI-based SigmaStudio™ for SHARC®. The development board is an optimized hardware design that utilizes two fourth generation SHARC processor, the ADSP-21489, running at 400MHz and the new 4K resolution UHD capable crosspoint transceiver.
All control and housekeeping functions on the EVAL-MELODY-5 platform are efficiently performed by a Blackfin® BF524 processor.
Dolby Atmos® and DTS:X decoders have been implemented and are certified by Dolby and DTS respectively at the IC level to reduce uncertainty regarding product certification. The UHD capabilities of the ADV7625 crosspoint transceiver support a 4K video pass through and allow HDMI embedded audio to be extracted, processed and either reinserted or rendered locally.
The hardware design allows cascading multiple SHARC processors to facilitate the development of systems that require more than two DSPs. The two DSPs execute Dolby Atmos and DTS:X decoders and the board may be interfaced to additional DSP processors for executing post processing routines. The ADV7625 HDMI Transceiver passes through video while extracting the embedded audio for processing by the DSPs and then optionally re-inserting the audio into the HDMI output stream.
Based on ADI’s award-winning SigmaStudio for SigmaDSP® digital signal processor tool, the SigmaStudio for SHARC tool is a programming, development and real-time tuning software environment that enables developers to graphically design and program audio applications for SHARC processors using an extensive, optimized library of more than 100 pre-built audio algorithms such as filtering, mixing, and dynamics processing, as well as basic low-level DSP functions and control blocks. SigmaStudio runs on a PC connected to the EVAL-MELODY-5 platform and helps software and audio engineers shorten their design times. SigmaStudio is unique in that it has proven to be friendly to audio designers while also meeting the needs of software engineers. It is easy to create software schematics by dragging the required modules from a library of about 100 different modules that are available. The CrossCore® Eclipse-based tools provide an easy development environment and are in used in conjunction with the SigmaStudio for SHARC.
