What factors should be considered when designing a DSP for a digital signal processing application

Signal acquisition, transmission, processing, storage, restoration.

Since it is digital signal processing, it must be a digital signal to be processed, because many signals in the real world are analog signals, so the general process of the digital signal processing system is as follows: external analog signal - "ADC - " DSP - "output; There are a lot of outputs here, depending on the DSP system you design; If your DSP is used with other MCUs, the output here will directly pass the data processed by the DSP to the MCU, and the MCU will take care of the rest; Similarly, if your DSP is connected to other specific chips (which are closely related to the system you are designing, such as audio chips, DACs, etc.), the DSP can send the processed data to those chips. Also, if you want to know more about typical applications, you can check out the software defined radio literature.

Hello dear! The general design process of designing a DSP application system is as follows: (1) Determine the system performance index:

2) Core algorithm simulation and verification: (3) Selection of DSP chips and other system components: (4) Hardware design and debugging; (5) software design and testing; (6) System testing and integration.

1) Determine the performance indicators of the system (2) Simulation and verification of core algorithms: (3) Select DSP chips and other system components

4) Hardware design and debugging; (5) software design and testing; (6) System testing and integration.

Try to write the hardware structure characteristics of +C54X+DSP, and analyze why it is particularly suitable for digital signal + processing?

Try to write the hardware structure characteristics of Mingzhou out of +C54X+DSP, and analyze why it is particularly suitable for digital information elimination number + processing? Hello dear, because C54XDSP has no decoder for its input and excitation bridge shielding module, so if you use digital signals for processing, you can transmit and calculate very quickly, which is determined by the characteristics of his equipment, I hope it can help you.

First of all, any sequence can be written as a real + imaginary part.

x(n) = r(n) +j*i(n)

The corresponding dft is x(k) = xep(k) + xop(k)x(n) is the real sequence, so as above, j i(n) does not exist, then its corresponding x(k) is a conjugate symmetric sequence, satisfying the condition xep(k)=xep*(n-k).

Looking at the problem, solve x(4-k), this question is 4 point DFT, from the formula we know that x(4-k)=x*(k) then the real part is unchanged, and the imaginary part is unchanged.

The negation is sufficient, so the answer is 1,j,-1,-j and b

x(n) is a real number, then x(k) is circumferentially conjugated and couple-symmetric, x(k)=x*(n-k). The answer is B.

FPGAs are made up of 'gates', i.e., AND NOT, etc.

FPGAs have better exploitability.

Dual-core quad-core processors, because the CPU is serial, the speed can only be increased by more and, and the FPGA is executed in parallel, so the computer with the FPGA as the core is many, many times stronger than the existing one.

In addition, FPGA's DSP Builder can already be customized on FPGA.

DSP is a processor that executes serial algorithms at high speeds and is commonly used in digital signal processing.

An FPGA is an array of logic gate circuits that can be used to implement a wide variety of combined digital circuits by changing the links of its internal logic units. Nowadays, due to the increasing number of logic units in FPGA, DSP processors (or soft cores of single-chip ARM) can be implemented on some high-specification FPGA chips.
