Fishman uses the Blackfin ADSP-BF532 running at a power-conserving 169MHz to perform 32bit audio effects processing in its AFX pedals.
Video collaboration upgrades media players
The combined efficiency of the RealVideo format and the performance of the Blackfin processor deliver a high-quality level of video playback traditionally not found in personal media players.
Dali found Blackfin to be the ideal fit in terms of power and cost savings for its series of DVR solutions, and the ability to update Blackfin with the latest video standards eliminates the fear that these DVRs will need to be replaced in the future.
Dali's DVRs are used for long periods of time and have the ability to support video in MPEG2, MPEG4, JPEG, Windows Media, and H.263/264 in a variety of screen sises and frame rates.
The high-use, high-functionality of the equipment was a main reason why Blackfin, with its efficiency in processing digital media while managing power, was used.

The performance of the Blackfin processor allows more robust image processing than earlier products, increasing accuracy and speed of transactions.
Upgrade for DSP development
Integrated development environment, debugger, C/C++ compiler, assembler, linker and simulator support Blackfin, SHARC and TigerSHARC processors.
Equally important for Dali was the ease of porting algorithms like MPEG4 Common Image Format and Digital 1 directly to the Blackfin processor because of its RISC-like instruction set.
These enhanced instructions and performance characteristics allow Blackfin to be considered in applications previously addressed primarily by ASICs, VLIW media processors, or hardwired chipsets.
"Video surveillance systems are routinely deployed throughout our world, enabling stronger security, and generating a plethora of video", said Dingfeng Chen, Director of Research and Development, Dali.
"Dali prides itself on manufacturing a leading DVR that is cost effective for the user".
"In order for us to deploy this solution, we used Blackfin for its power management and ability to future-proof our product".
"Through the use of ADI's VisualDSP++ for development and debugging, we simplified product development and decreased our time to market".
"Combining a RISC-like processor and the ability to decode any video algorithm, the Blackfin core architecture is ideal for media-intensive products like Dali's DVR solutions", said John Croteau, General Manager, Convergent Platforms and Services Group, Analog Devices.
"The Blackfin processors' efficiency in processing digital media comes from a combination of pure horsepower and the quad 8bit video ALUs that are embedded into the architecture".
"In a world full of evolving media standards, this gives users the ability to process all present and future standards".
Chen of Dali continued: "We found the ADSP-BF561 Blackfin to be ideal for our needs, particularly because it is comprised of two independent Blackfin cores in one processor".
"This enables us to extend processing performance, while retaining the low power attributes we needed".
"At the same time it was easier to use and allowed us to deliver a more cost-effective product".
