In this paper,a novel OFDM synchronization scheme with adaptive blind parameters detection is proposed,which utilizes a fast estimation method to obtain the key OFDM system parameters,including the FFT points number (2K/4K/8K Mode) and the length of guard *** parameters guarantee the accuracy of the further system ***,the proposed scheme is also a joint solution,which realizes the blind parameter detection,symbol recovery and frequency synchronization in the same process. Due to such novel scheme and its further sign-bit implement optimization,circuit implementation complexity of the synchronization block is reduced greatly to a quite impressive 8.3%of that while using the traditional scheme.

This paper proposes an AES algorithm against both differential power analysis and differential fault analysis and its hardware *** new algorithm emphasizes the feature of defending hardware against two kinds of side-channel attack *** the modified AES algorithm is much more complex than the original one,this paper exploits low hardware cost architecture to realize ***,a pipelined structure is adopted to achieve high throughput. Simulations show that this architecture can protect hardware against both differential power analysis and differential fault *** result demonstrates that this design achieves adequately high data throughput with low hardware cost.
Conventional clock skew scheduling for sequential circuits can be formulated as a minimum cycle ratio (MCR) problem, and hence can be solved effectively by methods such as Howard's algorithm. However, its applicat...

In this paper, we propose an inclusive NoC fault model incorporating both high-level abstraction and hardware structure. In high-level abstraction domain, we point out the deficiency of existing fault model as well as simulation procedure, and categorize faults according to their behavior on channel dependency graph CDG. We also introduce connectivity graph CG to identify connection break that faults might incur. In hardware structure domain, we include hardware faults with diverse granularities, and match each hardware fault to corresponding high-level abstraction fault. The fault model we propose shows convincing integrity, and brings more prospects to NoC fault handling.
