ADI ADSP BF70x系列民用无人机解决方案

ADI公司的民用无人机解决方案采用400MHz ADSP BF70x系列Blackfin处理器作为飞行控制器,用于室内定位的高性能图像处理(光流)和雷达信号处理.本文介绍了ADSP BF70x系列主要特性,框图和Blackfin+处理器核框图,ADI无人系统业务主要挑战和系统设计考虑,民用无人机信号链以及ADI无人系统业务主要特色产品.
The ADSP-BF70x processor is a member of the Blackfin® family of products. The Blackfin processor combines a dual- MAC 16-bit 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 architec-ture. New enhancements to the Blackfin+ core add 32-bit MAC and 16-bit complex MAC support, 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 low static power consumption. 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 memory (shown in Table 1), the 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 applica-tions span a wide array of markets, from automotive systems to embedded industrial, instrumentation, video/image analysis, biometric and power/motor control applications.
