Verilog HDL: Magnitude For a vector (a,b), the magnitude representation is the following: A common approach to implementing these arithmetic functions is to use the COORDINATE Rotation Digital Computer (CORDIC) algorithm. The CORDIC algorithm calculates the trigonometric functions of sine, cosine, magnitude, and phase using an iterative process. It is made up of a series of micro-rotations of the vector by a set of predetermined constants, which are powers of two. Using binary arithmetic, this algorithm essentially replaces multipliers with shift and add operations. In a Stratix™ device, it is possible to calculate some of these arithmetic functions directly, without having to implement the CORDIC algorithm.

The existence of numerous imaging modalities makes it possible to present different data present in different modalities together thus forming multimodal images. Component images forming multimodal images should be aligned, or registered so that all the data, coming from the different modalities, are displayed in proper locations. The term image registration is most commonly used to denote the process of alignment of images , that is of transforming them to the common COORDINATE system. This is done by optimizing a similarity measure between the two images. A widely used measure is Mutual Information (MI). This method requires estimating joint histogram of the two images. Experiments are presented that demonstrate the approach. The technique is intensity-based rather than feature-based. As a comparative assessment the performance based on normalized mutual information and cross correlation as metric have also been presented.

In computer vision, sets of data acquired by sampling the same scene or object at different times, or from different perspectives, will be in different COORDINATE systems. Image registration is the process of transforming the different sets of data into one COORDINATE system. Registration is necessary in order to be able to compare or integrate the data obtained from different measurements. Image registration is the process of transforming the different sets of data into one COORDINATE system. To be precise it involves finding transformations that relate spatial information conveyed in one image to that in another or in physical space. Image registration is performed on a series of at least two images, where one of these images is the reference image to which all the others will be registered. The other images are referred to as target images.

This includes the project using a stereo vision to catch the ball shot from a high pressure air cannon. The trajectory of the ball is located first by finding the ball color in the left and right camera. Then the trajectory is calculated to estimate the depth from the ball to the camera. The camera is calibrated to map the world COORDINATE to the camera COORDINATE and it can reach an accuracy over 90 . Enjoy

Wireless penetration has witnessed explosive growth over the last two decades. Accordingly, wireless devices have become much denser per unit area, resulting in an overcrowded usage of wireless resources. To avoid radio interferences and packet collisions, wireless stations have to exchange control messages to COORDINATE well. The existing wisdoms of conveying control messages could be classified into three categories: explicit, implicit, or hybrid.

Under the Energy Independence and Security Act of 2007 (EISA), the National Institute of Standards and Technology (NIST) was assigned “primary responsibility to COORDINATE development of a framework that includes protocols and model standards for information management to achieve interoperability of Smart Grid devices and systems…” [EISA Section 1305]. 35 This responsibility comes at a time when the electric power grid and electric power industry are undergoing the most dramatic transformation in many decades. Very significant investments are being made by industry and the federal government to modernize the power grid. To realize the full benefits of these investments—and the continued investments forecast for the coming decades—there is a continued need to establish effective smart grid 36 standards and protocols for interoperability.

基于DSP28035的高速永磁無(wú)刷直流電機(jī)驅(qū)動(dòng)系統(tǒng)，包括論文和軟硬設(shè)計(jì)資料。摘要參賽作品為基于DSP28035的高速永磁無(wú)刷直流電機(jī)驅(qū)動(dòng)系統(tǒng)。該系統(tǒng)以一臺(tái)額定轉(zhuǎn)速60 krpm的高速永磁無(wú)刷直流電機(jī)、交錯(cuò)并聯(lián)的Buck電路以及全橋電路為硬件平臺(tái)，以DSP28035為控制核心，實(shí)現(xiàn)了調(diào)壓調(diào)速功能和基于坐標(biāo)變換的無(wú)位置傳感器新技術(shù)。為實(shí)現(xiàn)該系統(tǒng)要求，本作品充分利用了DSP28035的資源例如：CLA模塊，模擬比較器、HPWM模塊以及AD轉(zhuǎn)換模塊等。AbstractThis work is the drive system for a high speed permanent magnet burshless dc motor based on DSP28035. The hardware platform consists of a BLDC motor(rated speed is 60000rpm), a Buck circuit and an inverter. Under the control of DSP28035, this system can achieve the goal of adjusting the motor’s speed with voltage and the function of sensorless control based on the COORDINATE transformation. By making full use of resources of the core, such as CLA, analog comparator, HPWM and AD converters, the whole system can meet the requirements.1 引言高速永磁無(wú)刷直流電機(jī)驅(qū)動(dòng)系統(tǒng)由于基波頻率較高（一般在1kHZ以上），利用逆變橋斬波進(jìn)行調(diào)速的控制方式通常會(huì)受到開(kāi)關(guān)管開(kāi)關(guān)頻率的限制，因此該系統(tǒng)多采用三相全橋前級(jí)加Buck電路進(jìn)承擔(dān)調(diào)壓調(diào)速的功能，而三相全橋主要承擔(dān)邏輯換相的功能。然而，傳統(tǒng)Buck電路所需電感的體積較大，增加了系統(tǒng)的體積，降低了系統(tǒng)的功率密度。
