Analog Devices Inc. has announced the immediate availability of its next-generation Blackfin processor family that delivers twice the performance and half the power consumption of conventional DSPs and embedded processors.

The ADSP-BF533 operates at 600MHz and performs 1.2 billion MACs, while the ADSP-BF531 operates at 300MHz and performs 600 million MACs. Both combine DSP performance with microcontroller functionality and embedded OS support to meet the computational demands and power constraints of embedded audio, video, and communications applications.

The Blackfin processors consume 0.15mW/MMAC at both 300MHz and 600MHz. They also feature Dynamic Power Management capability, wherein an on-chip switching regulator is added to permit programmable control of the core voltage - between 0.7V and 1.2V - from a single I/O supply.

The devices also support embedded OSs such as Embedded Linux, ThreadX, and Nucleus. In addition, the video optimizations within the Blackfin processors enable fully-programmable D1/VGA real-time video and multi-channel audio without the complexity of dedicated hardware or heterogeneous dual-core approaches.

Based on the Micro Signal Architecture jointly developed with Intel Corporation, the Blackfin processor family combines a 32-bit RISC-like instruction set with 16-bit dual MAC signal processing functionality and features attributes found usually found in general-purpose microcontrollers.

The new processors are pin-for-pin and code compatible and offer new levels of peripheral integration, including glueless connection to an array of ITU-R 656 video encoders and decoders, as well as high-speed ADC and DAC up to 65Msa/s.

A dedicated video port is included and is supported by a two-dimensional DMA structure that significantly reduces software overhead and system power consumption for real-time video applications. Also included are two dedicated serial ports that support up to eight channels of I2S audio.

The ADSP-BF533 is offered in two frequency grades - 500MHz (1 billion MACs) and 600MHz (1.2 billion MACs) for US$16.95 and US$19.95, respectively in quantities of 10,000 units. Both versions are packaged in 12-by-12mm 160-ball Mini-BGA package.

The ADSP-BF531 is available in 160-ball Mini-BGA versions at 400MHz, and is offered at US$5.95. The 300MHz LQFP version will be available in Q3 at $4.95.
