Higher operating frequencies may be obtained in digital systems by using wave-pipelining which permits clock frequencies higher that dictated by largest propagation delay between input and output. This requires proper selection of clock periods and clock skews so as to latch the output of combinational logic circuits at the stable periods. Major contributions of this paper are: proposal for the implementation...
Wave-pipelining enables a digital circuit to be operated at higher frequency. In the literature, only trial and error and manual procedures are adopted for the choice of the optimum value of clock and clock skew between the I/O registers of wave-pipelined circuits. The major contribution of this paper is the proposal for automating the above procedure for the ASIC implementation of wave-pipelined...
In the literature, pipelined systems require clock routing complexity and clock skews between different parts of the system. A circuit design technique such as wave-pipelining achieves high speed without the above limitations. Wave-pipelined circuit dispenses with the need for registers for storing the intermediate results and instead uses the inherent capacitance at the input to the various blocks...
In this paper a modified simple edge preserved denoising algorithm to remove salt and pepper noise in digital color images is presented. The algorithm has three steps: noisy pixel detection, replacement of noisy pixels, confirmation by comparing with a threshold. In additon a median filtering is added to improve the qualityof the image. The proposed algorithm prevents the smoothing of edges in the...
