Blackfin board hosts embedded Linux
development
A new board powered by a Blackfin processor provides designers with a cost-effective environment to develop embedded systems using an embedded Linux operating system.
The BF533 Stamp board, powered by the Analog Devices Blackfin processor, provides designers with a cost-effective environment to develop embedded systems using an embedded Linux operating system, the most used embedded OS in the world according to studies, and supports the development and porting of open source uClinux applications The Stamp board is part of a larger board support package (BSP) that includes a recent copy of the open source development tools and the uClinux 2.6.x kernel, which empowers signal processing and makes Linux suitable for a larger range of real-time applications

A/D convertor achieves a new level of 16bit data capture performance, with best-in-class 15bit ENOB and 10Msample/s throughput.
The Blackfin uClinux community hosts a number of open source application projects based on the Stamp board and accompanying daughterboards, such as a networked audio media node and networked oscilloscope.
In 2004, separate studies by Evans Data Corp (EDC) and Gartner DataQuest reflected the growth opportunity for embedded Linux.
The EDC study found that Embedded Linux remains the top embedded operating system (OS) choice among developers internationally and the Gartner study, in collaboration with EE Times Asia, found that embedded Linux is now the most commonly used operating system among Asian embedded developers.

In addition, the Department of Software Engineering at the University of Szeged in Szeged, Hungary recently added Blackfin to its GCC Code-Size Benchmark Environment (CSiBE).
CSiBE is a code size benchmark for the GCC compiler.
Researchers determined that the Blackfin compiler performed favourably against compilers for other microarchitectures.

"ADI distributes the 2.6.x kernel, with all the pre-emption, a more granular scheduler and more standardised way to build real-time applications for embedded developers".
"Analog Devices' Blackfin processor provides the critical technology for cost-conscious developers to roll out operating systems for their applications".
The Blackfin processor is the first in a new breed of 16/32bit embedded processors designed specifically to meet the computational demands and power constraints of today's embedded audio, video and communications applications.
The Blackfin processor family combines a 32bit RISC-like instruction set with 16bit 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.
The new Stamp BSPs feature 4Mbyte of Flash memory and 128Mbyte of SRAM, providing the memory needed to store the uClinux 2.6.x kernel, and Blackfin I/O headers enable simple connection to other prototype boards, such as daughtercards, for expansion.
