DSP digital signal processing skills for the use of signal processing provides a high function of the programmable processor, its characteristics are sensitive applicability, low power consumption, high efficiency and low cost. The following Xiaobian for everyone to share car audio DSP processing knowledge, hope to help you.
What is a DSP processor?
Digital Signal Processing (DSP) is a common microprocessor that processes a lot of information based on digital signals. Its operating principle is to accept the imitation signal, converted into a 0 or 1 digital signal. Then the digital signal is corrected, deleted and strengthened, and the digital data is interpreted back to imitate the data or practice environment pattern in other system chips. Not only is it programmable, but it is designed to run at a speed of tens of millions of messy instructions per second, far surpassing the general purpose microprocessor and becoming the increasingly premier computer chip in the digital electronic world.
DSP processor can control the digital signal with a fixed program, using the strength of the frequency to create a sound field, the auditory environment to create a space like the opera house feeling. It may also be able to embellish the personality of music into genres such as Jazz and Pop. Its strong data processing ability and high speed are the two most commendable features.
DSP has several advantages:
1. It is not sensitive to the tolerance of component value, and is little affected by external factors such as temperature and environment; 2. Simple completion integration; 3.VLSI can be time-sharing multiplexed, sharing processors; 4. It is convenient to adjust the coefficient of the processor to end the adaptive filtering; 5. The function of imitation processing can not be completed: linear phase, multi-sampling rate processing, cascade, easy storage, etc.; 6. Can be used for very low frequency signals.
