1. Retiming, which can optimize the rapidity, area and functional extravagance through moving the sequential elements and change the number of sequential elements.

2. We propose an retiming algorithm which can quickly optimize sequential circuits. We have conducted some experiments on the ISCAS89 benchmarks and the results sustain our opinion.

3. Retiming eliminate the digital time domain pulse distortion, in order to downlink clock recovery circuit to accurately signal reception.

4. This paper proposed a new algorithm of retiming which can be combined well with other combinational optimization methods to speed up logic circuits.

5. The effectivelyretiming determining algorithm is key of retiming, so it is the key of sequence adjust strategy.

6. In the conditions of implementing many display functions, we adopt power save mode, gating clock and retiming method to reduce power consumption.

7. This paper reviews the theory, method and application on retiming in synchronous logic circuit, which has been developed since 1980s. Prospect is also given for retiming applications.

8. In order to eliminate the sequence conflict of synchronous sequential circuit and shorten the designable time of Integrated Circuits, the algorithms of retiming is deeply researched in this paper.
