Leading Biometric Fingerprint Provider Selects Blackfin Processor For Overall Cost And Power Consumption Reduction

Norwood, MA - Analog Devices, Inc. announced Suprema, Inc., a leading fingerprint solution provider for PC-based and other embedded applications, has selected Blackfin® to drive its Unifinger™ SFM3000 and SFM3500 fingerprint-recognition modules. Leveraging the Blackfin Processor, the Unifinger is able to store thousands of fingerprints in internal memory and provide a host of biometric functions, including enrollment, one-to-one verification and one-to-many identification. Additionally, the processor’s low power consumption makes the Unifinger module ideal for battery-operated biometrics devices, in which low power is critical.

Offering OEMs (original equipment manufacturers) a choice of fingerprint sensors – optical, thermal, capacitive and electric field – Suprema developed the UniFinger for applications such as computer, door, and safe- and security-box access control. Designing with Blackfin provided Suprema with access to a rich set of peripherals connected to the core via several high-bandwidth busses; as a result, Suprema gained greater flexibility in system configuration as well as overall system performance.

“It was critical that we reduce overall cost and power because our modules are often deployed in battery-operated biometrics devices,” said Young S. Moon, Director, Suprema, Inc. “Unlike other processors that only allow for adjustments in the frequency of operation, the Blackfin Processor allows us to vary both voltage and frequency, which substantially reduces power consumption.”

Continued Moon: “The Blackfin also helped us to significantly reduce costs by providing a full complement of peripherals and interfaces, including a UART (universal asynchronous receiver/transmitter) and SPI (serial peripheral interface). Choosing the Blackfin was right for us because we didn’t need to sacrifice performance to reduce costs and power dissipation.”

In addition to Blackfin, Suprema made full use of Analog Devices’ simulation tools, using the company’s VisualDSP++ software, an integrated software development and debugging environment (IDDE) that enabled Suprema to manage its design projects from start to finish within a single interface. Suprema also used ADI’s VisualDSP++ Kernel (VDK) library for task scheduling and inter-processor communication, enabling the company to take full advantage of the state-of-the-art scheduling and resource allocation techniques tailored specifically to address the memory and timing constraints of programming.

Added John Croteau, general manager, Convergent Platforms and Services Group, Analog Devices, Inc.: “Analog Devices’ Blackfin Processor has proven to be a perfect fit for a variety of convergent applications including biometric security, due to its low cost and low power dissipation. Additionally, ADI’s commitment to develop high-quality embedded tools, such as VDK, enables companies like Suprema to use example code more efficiently and eliminate the need to start projects from scratch, thus saving development and debugging time.”

Blackfin in Convergent Processing
Analog Devices’ Blackfin Processors embody a new breed of 16/32-bit embedded processor with the industry’s highest performance and power efficiency for applications where a convergence of capabilities – multiformat audio, video, voice and image processing; multi-mode baseband and packet processing; and real-time security and control processing -- are critical. It is this powerful combination of software flexibility and scalability that has gained Blackfin widespread adoption in convergent applications such as portable and networked media players; automotive telematics, biometrics, infotainment and driver assistance; satellite and terrestrial radio; and networked security systems.
