SHARC Roadmap - The History

DSP CollaborativeSince the introduction of the Analog Devices Inc (ADI) third generation SHARC® family, Danville Signal has been the leading supplier of general purpose DSP boards based on the SHARC. Our dspstak™ 21262sx board was the first commercially available board based on this architecture. It was announced the same day that Analog Devices announced the ADSP-21262 in August 2003.

Danville Signal has always had a strategic relationship with Analog Devices. We work very closely with a number of DSP product groups at ADI. During the last several years, we have focused our attention on the fourth generation SHARC family of DSPs. The SHARC has emerged as the dominant platform for high performance audio. Many of our customers have an interest in some aspect of digital audio, whether their focus is in instrumentation, telephony, commercial or professional sound applications. We have a strong background in these areas; our product line is well suited to meet a variety of digital audio needs.
The SHARC DSP has a very useful architecture for many other signal processing applications. SHARC DSPs perform both 32 bit fixed point and 32 or 40 bit IEEE floating point operations equally well. This means that you can write your DSP algorithms to use the data format that is most appropriate for its task and benefit from the inherit precision of a 32 bit processor. SHARC DSPs are fast and easy to program. Our dspstak™ and dspblok™ products are designed to take advantage of the SHARC architecture. This allows our customers to integrate our products into their unique applications with short development times and great results.

The SHARC 214xx Solutions  

SHARC processors have a long legacy. New designs are based on Analog Devices fourth generation SHARC processors. SHARCs have always been fast, the new SHARC includes three independent hardware accelerators, dedicated computation engines for FIRs, IIRs and FFTs! The ADSP-21469, ADSP-21489 & ADSP-21479 all have 5Mbits of RAM. This is 2.5x the memory of the older flagship, ADSP-21369. The ADSP-214xx retains the great features of the third generation as well. This includes the DAI, DPI, ASRCs  and other peripherals that has made the SHARC popular for many standalone audio, industrial and military applications. 

Danville's SHARC implementations routinely extend the SHARC DSP features with popular interfaces such as USB and Ethernet. Each implementation is supported by pin compatible development "ICE" versions. Our dspBootloader technology allows you to program our modules with special tools. 

Danville is committed to supporting the SHARC family of DSPs. Analog Devices continues to develop new exciting SHARC DSPs. You can learn more about Analog Devices' SHARC Roadmap on the Analog Devices web site.

XMOS Roadmap

XMOS processors are very useful as communication devices for audio. We are a third party developer with XMOS. We combine SHARC DSPs and XMOS processors to create high power signal processing engines with USB Audio Class 2 support. These modules also support DSP Concepts' Audio Weaver graphical signal processing tools via Danville's HID extensions to the basic XMOS USB code base.  

FPGA Roadmap

In our view, FPGAs have a complementary role with general purpose DSP processors. We have opted to partner with Altera and support their Cyclone family FPGAs. We are shipping our dspblok 21369+fpga based on Analog Devices ADSP-21369 and Altera's EP3C5 and EP3C25 Cyclone III. In 2014, we will be releasing ADSP-21469 – Altera Cyclone FPGA - SoC hybrids. These include Dual ARM Cortex A9 processors.

Stay tuned for further developments. There is always some new on the horizon and we'll be there.
