SHARC Roadmap

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 third 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.
Analog Devices is shipping the fourth generation SHARC DSP. The first important part is the ADSP-21469. With the ADSP-21469, ADI has returned to its SHARC roots. The ADSP-21469 has link ports, last seen in the ADSP-21161. SHARCs have always been fast, the new SHARC includes three independent hardware accelerators, dedicated computation engines for FIRs, IIRs and FFTs!  The ADSP-21469 has 5Mbits of RAM. This is 2.5x the memory of the current flagship, ADSP-21369. The ADSP-21469 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. You may want to checkout our new dspblok 21469 family of DSP Modules .

Danville is committed to supporting the SHARC family of DSPs. Analog Devices has announced a number of very exciting SHARC DSPs. You can learn more about Analog Devices' SHARC Roadmap on the Analog Devices web site.

Blackfin Roadmap

Blackfin processors have steadily gained traction since their introduction in 2001. The latest generation of the Blackfin offers a number of new features that we think our customers will find compelling.
Connectivity is increasingly important with today’s applications. Many of the newer Blackfins, include high speed USB with USB-On-The-Go support and Ethernet controllers. With their wealth of on-board peripherals, Blackfins make excellent communications processors in addition to their signal processing capabilities.

Danville’s dspblok 527 is the first of many Blackfin based modules that take advantage of the latest Blackfin technology. It will be supported by the dspblok 527+ICE. The ICE version is pin compatible with the production version and is supported by the free KIT version of Visual DSP++.

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 new Cyclone III FPGAs. We are shipping our dspblok 21369+fpga based on Analog Devices ADSP-21369 and Altera's EP3C5 and EP3C25 Cyclone III. In 2010, we will be releasing ADSP-21469 – Altera Cyclone FPGA hybrids.

Each ADSP-21469 based production board will be supported by a pin compatible development version that includes an ADI debugger (ICE) and connections for an Altera USB Blaster. This means that you can connect Visual DSP++ and Quartus simultaneously to your target during product development and then move directly to production with modification.

FPGAs can be used for glue expansion such as LVDS interfaces for high speed converters as well as algorithm acceleration. Software Defined radios (SDRs) are one of the attractive applications for this combo.

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