Product Details
This device is a member of the ADSP-BF70x Blackfin Digital Signal Processor (DSP) product family. The new Blackfin+ processor core combines dual-MAC 16-bit, 32-bit MAC and 16-bit complex MAC in to a state-of-the-art signal processing engine. It also combines advantages of a clean, orthogonal RISC-like microprocessor instruction set, and single-instruction, multiple-data (SIMD) multimedia capabilities within a single instruction-set architecture. Further new enhancements to the Blackfin+ core add cache enhancements, branch prediction and other instruction set improvements—all while maintaining instruction set compatibility to previous Blackfin products.
The processor offers performance up to 400 MHz, as well as lowest power consumption at <100mW. Produced with a low-power and low-voltage design methodology, they provide world-class power management and performance.
By integrating a rich set of industry-leading system peripherals and large on-chip memory, this Blackfin processor is the platform of choice for next-generation applications that require RISC-like programmability, multimedia support, and leading-edge signal processing in one integrated package. These applications span a wide array of markets, from automotive systems to embedded industrial, instrumentation, video/image analysis, biometric and control applications.
