In fact, if ARM is used for DSP, it is absolutely not cost-effective, and the multiplication and division method implemented by software is very slow, and it is not fast enough for DSP chips. DSP is relatively high-end, the main difficulty lies in the algorithm. If your algorithm is written well, it is very good to do, and the performance is much stronger than ARM. It's more difficult, because in addition to programming, important algorithms, you are the algorithmNo, there's basically no future.
dsp is a digital signal processing chip, 5000 and 6000 are the models of ti's dsp chip. The 5000 is mainly characterized by low power consumption, and the speed is generally 100-300Mhz, which is suitable for audio processing or still image processing. Such as fingerprint recognition, ip phones, mobile phone chips and so on. Divided into 54xx and 55xx two series. The innovative mp3 uses 5410. The 6000 is a ti high-speed dsp processing chip with a main frequency up to 1Ghz.
Of course, the problem also arose simultaneously, and I had toDidn't do a lot of experiments to find out. I recommend using mathlab/simulink before the system is finalized, and experimenting with several chips will give you more insight. I felt like I was going to be a real DSP engineer, and I had the most difficult time. I feel like a hero. Heh heh.
Suggest that you start to focus on, if you want to bias hardware on FPGA, DSP, ARM,. If you want to prefer software ARM, DSP, fpga. Now some FPGA has embedded ARM and DSPSome of the ARM also embedded DSP. The three are not very separated, are just tools, FPGA program design and other program design is not the same, should be called circuit design better, ARM program is software, DSP between the two. Personal opinion, the degree of combination with hardware: MCU embedded EDA DSP (the real DSP master is a mathematics class, Fourier and Laplace are frequent customers at home) difficulty varies from person to person, interest and attitude determine difficulty, so it can not be determined for your situation.
Although the four-way DSPTo a string of numbers, and use computational methods to extract useful information to meet the needs of our practical applications.
Digital Signal Processing, English: Digital Signal Processing, abbreviated as DSP, is a professional basic course for electronic information. Its basic concepts and analysis methods have penetrated into information and communication engineering, circuits and systems, integrated circuit engineering, biomedical engineering, physical electronics, navigation, guidance and control, electromagnetic field and microwave technology. Hydroacoustic engineering, electrical engineering, power engineering, aeronautical engineering, environmental engineering, etcDomain.
DSP is an abbreviation for Digital Signal Processing. Digital signal processing is a method to process and analyze signals through digital technology. In electronic engineering, DSP usually involves the digital signal filtering, transformation, encoding, decoding and other operations to achieve specific signal processing tasks.
But digital mobile phones can completely eliminate the phenomenon of echoes and call pauses. A DSP targets a real-world signal such as sound and uses mathematical operations to change its properties in order to get better resultsGood sound quality; The DSP also compresses the data (your voice), eliminates background noise, and enables your voice to be transmitted at a higher rate, thus providing unparalleled call quality with no annoying echoes. This is the simplest explanation of the purpose of DSP.
Narrowly refers to the MCU of the dsp chip generally refers to the MCU (microcontroller unit) dsp chip , DSP is a digital signalThe processor. Compared with other chips, dsp chip has enhanced the digital signal processing capability. An SOC is a specific dedicated chip. Non-programmable (the program is fixed). All of these belong to the single chip microcomputer (SCM) in a broad sense.
Compared with MCU, DSP chip has more suitable software and hardware resources for digital signal processing, and can be used for complex digital signal processing algorithms; (5) Use a special DSP chip to achieve.
General purpose microprocessors have been called microcontrollers, which are computer systems integrated into dsp chip in a chip. General purpose microprocessor is based on A medium microprocessor core, with A/D, FlashRAM and other functions and peripherals. A single chip microcomputer can extend a variety of products, maximize and application needs to match, reduce dsp chip power consumption and cost. Dsp chips are designed to process digital signals quickly.
For example, when we listen to songs, there are some different options for bass, pop, rock, blues, etc., and the harmonic sound of the song is different after we choose it. This is DThe role of SP. It can also be understood that music is an audio signal, the audio signal comes from the car host, CD player, navigation, etc., the audio signal is played from the speaker through the power amplifier, and the middle is modified by DSP. Application of DSP in car audio.
