Part 1: Why DSP? Advantages of DSP architecture and DSP over traditional Analog CircuitsComparison between DSP and MCU: 1. Faster processing speed 2. Built-in high-speed hardware multiplier? Enhanced multi-level pipeline (high-speed data computing capability) 3. Improved larger storage structure the haver structure has independent programs and data spaces. What is DSP? It is a microprocessor that integrates hardware, software, and various commands to

First talk about why noise is generated.In the transmission process, the signal is transmitted at high and low level analog signals. Due to the loss of high-frequency signals during transmission. As shown, the rising edge of the signal slows down. Rise time becomes longer.This is the key to the problem. When the same 1: to sample data, it is possible that Setup and Holdon can not meet. Causing problems with

, and cannot be modeled at all. Therefore, it is an unidentifiable problem. So without the idea of Higher Algebra, can the practical signal processing method extract local features for classification? This still does not answer the question of "A prior" classification, and is still trying to find a way to barely use it on a bad premise. How does one know that the local part of a Matrix actually corresponds

1. The frequency of the individual 0 points correspondsA single 0 point corresponding to a fraction of 1-az-1,a can be a complex number. When z is in the value of the unit circle, we can write this fraction as 1-rejθe-jω to analyze.2. Multiple polesIf the system's H[n] is a real number, then the frequency response of the system must have a conjugate symmetric 0 points or poles (the system frequency response is a real coefficient polynomial). For example, assuming that the system function has a p

Queuing.Conclusion:Shared memory allows two or more processes to share a given store, because the data does not need to replicate back and forth, so it is the fastest inter-process communication mechanism. Shared memory can be implemented through the mmap () mapping of ordinary files (in special cases, anonymous mappings), or through the System V shared memory mechanism. The application interface and principle are simple and the internal mechanism is complex. In order to achieve more secure com

VSync will eventually be distributed to listeners by Eventthread::threadloop (), MessageQueue in the current version. MessageQueue through the establishment of a connection with Eventthread to
