DSP (digital singnal processor) is a unique microprocessor that processes a large amount of information with digital signals. The working principle is to receive an analog signal, convert it to a digital signal of 0 or 1, and then to the digitalThe signal is modified, deleted, strengthened, and the digital data is interpreted back into analog data or real environment format in its dsp chip other system chip.
2, 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, no DSP chip is fast. 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 harder, because besides making it upProcess, important algorithm, if you can't do the algorithm, basically there is no future.
3, dsp is a digital signal processing chip, 5000 and 6000 are ti company dsp chip models. 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.
Difference: Different application scenarios. SCM is a system design scheme that integrates the CPU, timer and various interfaces of the computer on a chip.Can meet a variety of applications. Today's small appliances, such as induction cookers, refrigerators, washing machines, these products are developed by single-sided machines.
The difference between DSP and MCU: The memory structure is different. Neumann memory structure. In this architecture, only one memory space is connected to the processor core via a set of buses (an address bus and a data bus). Most DSPS adopt the Harvard structure, which divides the memory space into two, storing programs and data respectively.
Computing power: Since DSP focuses on digital signal processing tasks, itIt is usually superior to single-chip computer in floating-point computing power, high-speed processing, parallelism and so on. The computing power of single chip microcomputer is relatively low, but it usually has low power consumption characteristics. Internal memory: Microcontrollers usually have a large internal memory, including flash memory (for program storage) and RAM (for data storage). DSPS typically rely more on external memory, such as external RAM and flash memory.
The difference between the dsp chip and the MCU is still very big. The so-called MCU is a chip that integrates the cpu, ram, rom (eprom or eeprom), clock, timing/countingMultifunctional serial and parallel i/o ports. In addition to the above basic functions, some also integrate a/d, d/a, and even wireless communication functions (a trend in the development of single-chip microcomputer - system-on-chip soc). Low price, simple intelligent control function.
2, soft solution is to use CPU decoding, audio hard solution is through the sound cardDevice DSP chip decoding. The soft solution has to compromise the universality of the decoding device, so the efficiency and quality of the algorithm are discounted. The hard solution is decoded by a special DSP chip, so the quality and efficiency are high.
3, hard solution generally refers to the full hard solution decoding, decoding by the FPGA or audio DSP, high stability, as long as the input to the DSP or FPGA does not interrupt or no error, there will be no other unstable situation in the middle. Q7 dsp chip : Common digital music playback is CPU decoding chip, whyThe architecture of the sound is to string an FPGA between the CPU decoding chips.
Difference between DSP and MCU 1 Memory structure Different MCU use von. Neumann memory structure. In this architecture, only one memory space is connected to the processor core via a set of buses (an address bus and a data bus). Most DSPS use the dsp chip Harvard structure, dividing the memory space into twoTwo, respectively store the program and data. 2 Fixed point computation Most DSPS use fixed point computation instead of floating point.
Different application scenarios. Single chip microcomputer is a system design scheme, the computer's CPU, timer and a variety of interfaces integrated on a chip, can meet a variety of applications. Today's small appliances, such as induction cookers, refrigerators, washing machines, these products are developed by single-sided machines.
