blackfin

The Blackfin is a family of 16- or 32-bit microprocessors developed, manufactured and marketed by Analog Devices. The processors have built-in, fixed-point digital signal processor (DSP) functionality supplied by 16-bit Multiply–accumulates (MACs), accompanied on-chip by a small microcontroller.〔(【引用サイトリンク】title=Blackfin processor architecture overview )〕 It was designed for a low-power, unified processor architecture that can run operating systems while simultaneously handling complex numeric tasks such as real-time H.264 video encoding.〔(【引用サイトリンク】title=H.264 BP/MP Encoder )〕〔(【引用サイトリンク】title=H.264 BP/MP Decoder Library )〕 There are several hardware development kits for the Blackfin. Open-source operating systems for the Blackfin include uClinux.
== Architecture details ==

Blackfin processors use a 32-bit RISC microcontroller programming model on a SIMD architecture, which was co-developed by Intel and Analog Devices, as MSA (Micro Signal Architecture).
The architecture was announced in December 2000, and first demonstrated at the Embedded Systems Conference in June, 2001.
It incorporates aspects of ADI's older SHARC architecture and Intel's XScale architecture into a single core, combining digital signal processing (DSP) and microcontroller functionality. There are many differences in the core architecture between Blackfin/MSA and XScale/ARM or SHARC, but the combination was designed to improve performance, programmability and power consumption over traditional DSP or RISC architecture designs.
The Blackfin architecture encompasses various CPU models, each targeting particular applications.〔(list of products )〕
