Optimization of H.264/AVC Video Coding Based on DSP Platform,ompared with previous work, it is characterized that the degree of code parallelism is improved through the reasonable arrange of data stream and module division without any loss in coding performance. The simulated results indicate that this efficient implementation can improve the speed of encoder by 30%.

A Novel Convolutive ICA for Seismic Data Denoising, and applying a fast-converging kurtotic method for convolutive mixtures to seismic data denoising. The validity and feasibility of the proposed method was verified by both the synthetic and real seismic records. Results show that the average SIR of the seismic signals was improved about 7 dB after processed by the novel method.

Eliminating Redundant Memory Operations at Function Calls,roprocessor applications. Unfortunately, existing compilers do excessively context saving at function calls, which increases chances to access memory and decreases overall performance. In this paper, an optimal compiler algorithm is proposed to make context saving more efficient by utilizing an exte
