Blackfin DSP debuts

Analog Devices (ADI) has revealed its new Blackfin family of 16-bit digital signal processors (DSPs) that integrate the Micro Signal Architecture jointly developed with Intel Corporation.

The new Blackfin DSP operates at 300MHz, delivering up to 600 million multiply accumulate instructions per second (MMACs) and sports a power consumption as low as 42 mW at 0.9 V.

The first DSP in the Blackfin DSP family includes a Peripheral Component Interconnect (PCI) bus and Universal Serial Bus (USB) Device interfaces. It also integrates 2.4 Mbits of SRAM and a level one memory that can be configured as Cache or SRAM.

With video arithmetic logic units (ALUs) processing up to four 8-bit math operations in a single clock cycle, software can efficiently support video compression, motion estimation and Huffman coding algorithms used by video and image processing standards such as MPEG2, MPEG4 and JPEG.

The ADSP-21535 Blackfin DSP is also the first DSP with Dynamic Power Management, allowing independent adjustment of both voltage and frequency to minimize the energy consumed by each processing task. A power management companion chip from ADI manages the voltage and battery charging functions in Blackfin DSP-based designs.

Dynamic Power Management reduces power consumption using advanced clocking control, five core power down modes and independent power down states for each of the functional blocks within the DSP core, memory blocks and peripherals.

Two Blackfin DSP models are scheduled for September 2001 sampling and first quarter 2002 production. The ADSP-21535PKCA-200, operating at 200 MHz, has a suggested resale price of $27 per unit in quantities of 10,000 units. The ADSP-21535PKCA-300, operating at 300 MHz, is priced at $34 per unit in quantities of 10,000 units.
