:ADI), a global leader in high-performance semiconductors for signal processing applications, today announced the availability of four new network-enabled Blackfin Processors designed for embedded audio, video and communications applications. Representing the continued progression of the company's Blackfin Processor portfolio, these newest offerings extend scalability, portability and connectivity to new embedded products that include IP set-top boxes, portable and networked media players, automotive safety, driver assistance and networked security gear.

The Blackfin architecture combines the robust audio and video processing capabilities of digital signal processors (DSPs) and media processors with the programming ease of embedded 16/32-bit microprocessors. The newly available ADSP-BF534, BF536 and BF537 processors and the BF566eM30 eMedia Platform are highly integrated system-on-chip (SOC) solutions for the next generation of embedded, network-connected applications. By combining industry-standard network interfaces with a high-performance processor core, users can develop cost-effective solutions quickly without the need for costly external components. These new products continue to make the Blackfin Processor the architecture of choice for next-generation applications that require control and network processing, multimedia support and leading-edge signal processing in one, homogeneous architecture.

"The availability of the latest Blackfin Processors expands our portfolio of programmable, expandable and upgradeable general-purpose processors, enabling our customers to rapidly introduce new classes of media-rich, networked devices," said John Croteau, general manager, Media Platforms and Services Group, Analog Devices, Inc. "In the past year, the Blackfin Processor has been designed into thousands of applications such as automotive driver assistance and telematics systems, wireless handsets, security and surveillance cameras, networked media players, IP set-top boxes, biometric sensing devices and videophones. Each of these customers chose the Blackfin Processor because it meets the challenge of creating new classes of media-rich, networked devices with a minimal bill of materials The list of components that make up a system. For example, a bill of materials for a house would include the cement block, lumber, shingles, doors, windows, plumbing, electric, heating and so on. , breakthrough power efficiency and fast time-to-market."

IP-based video delivery is poised to enter the mainstream, now that service providers are gaining the ability to offer digital TV and video-on-demand services over broadband IP connections Blackfin Processors have already made an immediate impact on the emerging market, enabling IP-based television, voice and videoconferencing services over the existing broadband infrastructure. Designed specifically for IP set-top boxes, the high-performance media processing and networked capability of the Blackfin BF566eM30 allows IP TV service providers to equip their set-top boxes with the flexibility to support advanced codecs The following is a list of codecs. Audio codecs
Non-compression formats
  • Audio Interchange File Format (AIFF, container format)
  • Resource Interchange File Format (RIFF, container format)
 such as H.264 and VC1, legacy codecs such as MPEG (Moving Pictures Experts Group) An ISO/ITU standard for compressing digital video. Pronounced "em-peg," it is the universal standard for digital terrestrial, cable and satellite TV, DVDs and digital video recorders (DVRs). 2, and guarantee the programmability to ensure future upgrades and standards. Blackfin's unique combination of control and network processing, multimedia support and signal processing is optimized for the security, packet, voice and video processing challenges found in new classes of IP set-top boxes, gateways and Internet access devices.

"IP-based video delivery has become a reality," said Michelle Abraham, senior analyst, In-Stat/MDR. "For years, providers talked about supplying television over phone networks. But until recently they couldn't deliver on that promise in a cost-effective manner, because they lacked a processor architecture that afforded the cost structure and freedom of design required to satisfy the demands of television, data and voice. The arrival of flexible processors like ADI's Blackfin, are making all media decoding and encoding fully software-programmable and enabling mass-market development of advanced codecs for IP TV and other applications."

The new Blackfin Processors are ideal for applications such as portable and networked media players; automotive safety and driver assistance; and networked security. The ADSPBF534 processors' system peripherals include an integrated CAN 2.0B controller, a Two Wire Interface controller, two UART (Universal Asynchronous Receiver Transmitter) The electronic circuit that makes up the serial port. Also known as "universal serial asynchronous receiver transmitter" (USART), it converts parallel bytes from the CPU into serial bits for transmission, and vice  ports, an SPI (1) (Stateful Packet Inspection) See stateful inspection.

 request lines, nine general-purpose 32-bit timers (eight with PWM (Pulse Width Modulation) A modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. Like its fixed-width pulse density modulation (PDM) cousin, the output switching transistor is on more of the time for a  capability), a real-time clock, a watchdog timer, 48 general-purpose I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output.

 pins and a Parallel Peripheral Interface The Parallel Peripheral Interface (PPI) is a peripheral found on the Blackfin embedded processor.

The PPI is a half-duplex, bi-directional port that is designed to connect directly to LCDs, CMOS sensors, CCDs, video encoders (video DACs), video decoders (video ADCs)
. The ADSPBF536/ 537 further extends the feature set by adding an integrated IEEE-compliant 802.3 10/ 100 Ethernet MAC and an enhanced DMA system for high network-bandwidth capability.

ADI's Blackfin Processor is the first in a new breed of 16/32-bit embedded processors designed specifically to meet the computational demands and power constraints of today's embedded audio, video and communications applications. Based on the Micro Signal Architecture (MSA (Metropolitan Service Area) An urban area with at least 50,000 people plus surrounding counties. There are 306 MSAs and 428 RSAs (rural service areas) in the U.S. MSAs and RSAs are used to allocate cellular licenses. ) jointly developed with Intel Corporation, the Blackfin Processor family combines a 32-bit RISC-like instruction set with 16-bit dual multiply accumulate (MAC) signal processing functionality and ease-of-use attributes found in general-purpose microcontrollers. Dynamic Power Management enables breakthrough power consumption by allowing the simultaneous adjustment of operating frequency and voltage under application control. Because of their code compatibility, all Blackfin Processors provide portability of design.

Blackfin Processors are fully supported by ADI's CROSSCORE Tools product line, which consists of the VisualDSP++ development and debugging environment, EZKIT Lite evaluation kits, EZ-Extender daughter boards and emulators. The easy-to-use VisualDSP++ integrated development environment See IDE.
