Designing the lowest density maximum-distance separable (MDS) array codes has gained much attention in recent years due to the optimal redundancy and minimum update penalty (lowest density) of such codes. However, the existing lowest density MDS array codes of distance 4 have extremely strict constraints on the code length, which makes them impractical. In particular, most of them require the code...
A novel loss less compression algorithm known as compression by sub string enumeration (CSE) is analyzed and modified. The CSE compression algorithm is a block-based, off-line method, as is the case with enumerative codes and the block-sorting compression scheme. First, we propose an encoding model that achieves asymptotic optimality for stationary ergodic sources. The codeword length attained by...
Multi-core processor Simulation Platform is always a very important tool in modern multi-core processor design for the system-level design and evaluation. In this paper, a multi-core processor simulator is proposed by modifying Simple Scalar v3.0to simulate parallelized multi-core programs. Shared memory is used for the communication between different cores, which is the communication network among...
The main idea of this article is through using Multi-level index and instruction abstract technology to improve the decode methods of the traditional MIPS instruction set simulation, The experiments show that this method can greatly improve the efficiency of program execution.
PRAM CREW parallel algorithms requiring logarithmic time and a linear number of processors exist for sliding (LZ1) and static dictionary compression. On the other hand, LZ2 compression seems hard to parallelize. Both adaptive methods work with prefix dictionaries, that is, all prefixes of a dictionary element are dictionary elements.Therefore, it is reasonable to use prefix dictionaries also for the...
We propose a multimodal speaker segmentation algorithm with two main contributions: First, we suggest a hidden Markov model architecture that performs fusion of the three modalities: a multi-camera system for participant localization, a microphone array for speaker localization, and a speaker identification system; second, we present a novel method for dealing with overlapped speech segments through...
This paper studies efficient complex valued matrix manipulations for multi-user STBC-MIMO decoding. A novel method called Alamouti blockwise analytical matrix inversion (ABAMI) is proposed for the inversion of large complex matrices that are based on Alamouti sub-blocks. Another method using a variant of Givens rotation is proposed for fast QR decomposition of this kind of matrices. Our solutions...
