嵌入式开发经验总结

A comprehensive book that covers digital microprocessor sound and music synthesis, and features heretofore unpublished techniques that are practical only with microprocessors. Standard linear techniques for microprocessor applications are discussed. Also covered musical applications for the newer and more powerful 16-bit microprocessors are explained, and all phases of waveform shaping and filtering as applied by digital devices to electronic music generation.

Designing Software Synthesizer Plugins in C++ provides everything you need to know to start designing and writing your own synthesizer plugins, including theory and practical examples for all of the major synthesizer building blocks, from LFOs and EGs to PCM samples and morphing wavetables, along with complete synthesizer example projects. The book and accompanying SynthLab projects include scores of C++ objects and functions that implement the synthesizer building blocks as well as six synthes

where affordable smart-phones with a variety of sensors are readily available to the public. The capability of the onboard sensing make them ideal for developing navigation applications, whereby relevant information is communicated to users based on their actively or passively determined location. While outdoor navigation is a well established technological field and available for most modern smartphones, analogous techniques for indoor environments are still in their infancy. In this paper, we describe a unique architecture for indoor navigation that integrates behavior recognition, multisensor indoor localization, and path-planning in order to pro-actively provide directions without direct input from users. To our knowledge, this is the first architecture that attempts to integrate the core navigation components of pathplanning and localization with intent prediction towards a
