In this paper,the characteristic of computer video signal is analyzed from both time-domain and frequency-domain,and the application of the digital correlation analysis and digital spectral analysis in the pick-up of synchronous information is emulated and testified in MATLAB,whi.

Data dependence analysis is one of the most important techniques for the exploitation of the inherent parallelism in sequential programs, but traditional automatic data dependence analysis can not manipulate the complexities of real applications.

The dependence difference inequality test for analyzing data dependencies of multi-dimensional arrays in software pipelining field is more efficient and accurate than other traditional data dependence analysis methods by using more strict inequality limitations.
