Objective For a long time the data structure and algorithm of things forgotten, recently want to revisit this knowledge. So I wrote a series of 1. Time Test Because this part uses a practical method to analyze the data structure and algorithm detection, so avoids the use of the Big O analysis here, but uses the met

FPGA and Simulink combined real-time loop series-openingToday, the FPGA development process is bound to involve a process: verification simulation, validation in many cases is done in MATLAB, and most of the simulation of the beginners are using Modelsim simulation software. For example, design a signal filter module, verify that the filter module is in MATLAB design verification, the module design paramete

default is also an analysis It is important to choose a regular ID, and an ID that is too random (such as a Java UUID) is not conducive to querying On the last point, the individual believes that there are several factors:One (perhaps not the most important) factor: the above-mentioned compression algorithm, is the posting list in the large number of ID compression, if the ID is sequential, or there is a common prefix, such as a certain regu

blackboard: Fourier told us that any periodic function, can be seen as a different amplitude, different phase sine wave superposition. In the first example, we can understand that by using different strokes of different keys and different points of time, you can combine any piece of music. One of the methods through time domain and frequency domain is Fourier analys
