Blackfin Processor-based Acoustic Measurement Equipment General Hardware Platform

This dissertation gives a use ADI's Blackfin processor (family) structures common hardware platform, based on embedded operating systems, such as uCLinux, to provide general hardware platform of the acoustic characteristics instrument. Major research using Blackfin processors DSP + MCU structures of the acoustic measurement equipment common hardware platform.The author of the dissertation used Blackfin processor's new features which combines high-performance DSP and the powerful MCU, smart instrumentation typical traditional independent DSP chips and microcontroller or MCU to further simplify the structure for only use a high-performance processor of Blackfin the core structure, developed a general hardware platform. Thereby reducing the size of the smart instrumentation, smart hand-held instruments to reduce the power consumption and provide longer hours of work.This dissertation analyses the new processor DSP + MCU of the proposed based on ADI's ADSP BF533 chip design and structural framework. Detailed description of a common hardware platform of the design process, the functions of each module and inter-interface, high-speed PCB board layout principles and attention to the matter.Hardware platform eventually completed the uCLinux embedded, to achieve the intended function, can be used in handheld acoustic characteristics of measuring instruments.In the latter part of plans to continue in-depth study into the RTLinux to meet the applications of real-time highly.
