Matrix inversion is widely used in scientific calculation and the computation complexity grows in exponent with the matrix dimension. In order to accelerate the computation speed, a block LU decomposition matrix inversion method based on multi-core processing is proposed. Parallel programs for 20*20 matrix inversion are developed and mapped onto an in-house developed multi-core platform, in which...
Universal bus interface is very helpful for improving the popularity of the device or equipment on both SoC integration and board level computing system design. Because of the diversity of bus interface accessing protocol, universality is usually unable to be achieved in a common interface design. Through introducing the concept of sequence configuration, a method of designing universal bus interface...
A VLSI design of complex Quadrature Mirror Filterbank (QMF) for MPEG-4 High Efficiency Advanced Audio Coding (MPEG-4 HE-AAC) decoder using resource-sharing technique is proposed. The algorithm that uses conventional discrete cosine transform of type IV(DCT-IV) to optimize complex-QMF is derived in this paper. By using the proposed algorithm, the VLSI design of complex valued analysis quadrature mirror...
New tendencies envisage multiprocessor systems-onchips (MPSoCs) as a promising solution for the high performance Embedding System. And the key challenge is how to improve the communication efficiency. Network on Chip (NoC) has been considered as a new paradigm in the next generation communication architecture for its extensibility and power efficiency. The router is the fundamental unit of NoC. In...
With the development of IC technology and the increasing processing power requirement, more and more processing cores are being integrated into one single chip. One of the key problems is the communication efficiency between the processing cores, and network on chip (NoC) has been proposed as prospect architecture. In this paper, scalability issue of 2-D mesh based NoC is analyzed. First, a mesh based...
MPEG-2 AAC is the widely used audio standard and getting more popular for commercial use. In the AAC, the filterbank tool, which is composed of IMDCT, windowing and overlap-add, has the highest computation complexity. In this three steps, IMDCT is the important component. Hence, most published filterbank algorithms focus mainly on the implementation of IMDCT but overlook the relevancy between the...
