Short Content: Abstract: According to the design requirements, uses in the Matlab signal processing toolbox's filter, may design very conveniently meets the application requirement not after the quantification IIR filter, and further uses the VHDL language to describe, after translation, function simulation, synthesis and succession simulation might realize on FPGA. This design extension is good, in actual use, but revises the periphery parameter to change filter's frequency response suitably, performs according to the different request on different scale's FPGA to realize. ...

Short Content: The abstract under the Matlab/Simulink environment, designs the DSP procedure with the presente in figures and diagrams way, but reduced program design. Using Embedded Targetfor T1 C2000 the DSP tool bag, designs DSP the ADC conversion routine; Using the Simulink digital signal processing tool bag, designs the FIR filter clamour to carry on filter processing; Gives when the revision production C language procedure how to enable DSP to move correctly. The design procedure moves correctly on the TM$320LF2407A processor.Key word ...

Short Content:     The FIR filter's structure main right and wrong recursive structure, has not output the input the feedback. And the FIR filter are very easy to obtain the strict linear phase characteristic, avoids processing the signal to produce the phase distortion. But the linear phase manifests in the time domain is merely h (n) in the time detention, this characteristic in profile transmission systems and so on image signal processing, data transmission is very important. In addition, he will not ...

Short Content: Abstract: The real-time data exchange (RTDX) are one kind of very outstanding real time data transmission technology which TI Corporation promotes, was the DSP system's software debugging has provided one brand-new method. It uses DSP the internal simulation logic and the JTAG connection realizes between the main engine and target machine's data exchange. Does not take I/0 resources and so on DSP system bus and serial port. The data transfer definitely may in the application procedure backstage movement. Is very ...

Short Content: Abstract: In based on the FPGA complex number system's simulation test, the designer faces each kind of challenge frequently. Take the digital image processing system's simulation as an example. If uses the complete simulation test method, then test vector's quantity will be very huge; If uses the conventional method. Not only the efficiency is not high. Moreover is possibly unable to achieve the simulation test the goal. In view of this difficult problem, proposed that one kind carries on the ...
