DSP（digital singnal processor）是一种独特的微处理器，是以数字信号来处理大量信息的器件。其工作原理是接收模拟信号，转换为0或1的数字信号，再对数字信号进行修改、删除、强化，并在其他系统芯片中把数字数据解译回模拟数据或实际环境格式。它不仅具有可编程性，而且其实时运行速度可达每秒数以千万条复杂指令程序，源源超过通用微处理器，是数字化电子世界中日益重要的电脑芯片。它的强大数据处理能力和高运行速度，是最值得称道的两大特色

该类方法主要指的是活动轮廓模型（active contour model）以及在其基础上发展出来的算法，其基本思想是使用连续曲线来表达目标边缘，并定义一个能量泛函使得其自变量包括边缘曲线，因此分割过程就转变为求解能量泛函的最小值的过程，一般可通过求解函数对应的欧拉(Euler．Lagrange)方程来实现，能量达到最小时的曲线位置就是目标的轮廓所在。

Guided vehicles (GVs) are commonly used for the internal transportation of loads in warehouses, production plants and terminals. These guided vehicles can be routed with a variety of vehicle dispatching rules in an attempt to meet performance criteria such as minimizing the average load waiting times. In this research, we use simulation models of three companies to evaluate the performance of several real-time vehicle dispatching rules, in part described in the literature. It appears that there is a clear difference in average load waiting time between the different dispatching rules in the different environments. Simple rules, based on load and vehicle proximity (distance-based) perform best for all cases. The penalty for this is a relatively high maximum load waiting time. A distance-based rule with time truncation, giving more priority to loads that have to wait longer than a time threshold, appears to yield the best possible overall performance. A rule that particularly considers load-waiting time performs poor overall. We also show that using little pre-arrival information of loads leads to a significant improvement in the performance of the dispatching rules without changing their performance ranking.

The TAS3204 is a highly-integrated audio system-on-chip (SOC) consisting of a fully-programmable, 48-bit digital audio processor, a 3:1 stereo analog input MUX, four ADCs, four DACs, and other analog functionality. The TAS3204 is programmable with the graphical PurePath Studio™ suite of DSP code development software. PurePath Studio is a highly intuitive, drag-and-drop environment that minimizes software development effort while allowing the end user to utilize the power and flexibility of the TAS3204’s digital audio processing core. TAS3204 processing capability includes speaker equalization and crossover, volume/bass/treble control, signal mixing/MUXing/splitting, delay compensation, dynamic range compression, and many other basic audio functions. Audio functions such as matrix decoding, stereo widening, surround sound virtualization and psychoacoustic bass boost are also available with either third-party or TI royalty-free algorithms. The TAS3204 contains a custom-designed, fully-programmable 135-MHz, 48-bit digital audio processor. A 76-bit accumulator ensures that the high precision necessary for quality digital audio is maintained during arithmetic operations. Four differential 102 dB DNR ADCs and four differential 105 dB DNR DACs ensure that high quality audio is maintained through the whole signal chain as well as increasing robustness against noise sources such as TDMA interference. The TAS3204 is composed of eight functional blocks: Clocking System Digital Audio Interface Analog Audio Interface Power supply Clocks, digital PLL I2C control interface 8051 MCUcontroller Audio DSP – digital audio processing 特性 Digital Audio Processor Fully Programmable With the Graphical, Drag-and-Drop PurePath Studio™ Software Development Environment 135-MHz Operation 48-Bit Data Path With 76-Bit Accumulator Hardware Single-Cycle Multiplier (28 × 48)

用TI公司TMS320F2812来控制无刷直流电机（三相无刷直流电机），需要的程序是把霍尔元件（怎么捕获转子信息无所谓，主要是怎么把捕获的信息转换成脉宽调制输出信号）捕获到的转子信息转换成6路PWM脉冲输出信号的源程序，是用C语言来编的
