Analog Devices BF518F FMC Development Kit
The ADSP-BF512/ADSP-BF512F, ADSP-BF514/ADSPBF514F, ADSP-BF516/ADSP-BF516F, ADSP-BF518/ADSPBF518F processors are members of the Blackfin® family of products, incorporating the Analog Devices/Intel Micro Signal Architecture (MSA). Blackfin processors combine a dual-MAC state-of-the-art signal processing engine, the advantages of a clean, orthogonal RISC-like microprocessor instruction set, and single-instruction, multiple-data (SIMD) multimedia capabilities into a single instruction-set architecture.
The processors are completely code compatible with other Blackfin processors.

BF518F FMC CPU Evaluation Kit provides a complete development platform for designing and verifying applications based on the Analog Devices Blackfin BF51xF family of DSP processors. The kit enables designers to use the BF518F controller with on board standard peripherals and expand their prototype system by enabling customization through the FMC LPC expansion slot.
The Analog Devices BF518F FMC Development Kit, designed by and available exclusively from Avnet Electronics Marketing, provides a simple-to-use platform for hardware and software engineers designing with the Analog Devices BF518F low-power Blackfin® processor and the Microsoft .NET Micro Framework.
The board can operate either as a standalone, or as an FMC Mezzanine Module connected to any VITA 57.1-compliant carrier board. By providing a convenient development platform for applications that combine FPGAs and embedded processors with advanced networking capability, it has never been easier to include signal processing in your next design.
