In this paper we focus on the design methodology to propose a design that is more flexible than ASIC solution and more efficient than the processor-based solution for H.264 video decoder. We explore the memory access bandwidth requirement and different software/hardware partitions so as to propose a configurable architecture adopting a DEM (Data Exchange(More)
In this paper we propose some optimization techniques to achieve the goal of real-time decoding of the new generation video such as VC-1, H.264, and AVS on embedded processors. We optimize the VC-1/H.264/AVS video decoders from a variety of viewpoints including algorithmic complexity reduction, memory access minimization, branch minimization, and zero(More)
In this paper, we propose a joint algorithm/code-level optimization scheme to make it feasible to perform real-time H.264/AVC video decoding software on ARM-based platform for mobile multimedia applications. In the algorithm-level optimization, we propose various techniques like fast interpolation scheme, zero-skipping technique for texture decoding, fast(More)
—The RSA cryptosystem is one of the widely used public key systems. The security of it is based on the intractability of factoring a large composite integer into two component primes, which is referred to as the RSA assumption. So far, the Quadratic Sieve (QS) is the fastest and general-purpose method for factoring composite numbers having less than about(More)
A proxy convertible authenticated encryption (CAE) scheme allows an original signer to delegate his signing power to a proxy signer such that the proxy signer can generate an authenticated ciphertext on behalf of the original signer. The generated authenticated ciphertext can only be decrypted and verified by the specific recipient instead of everyone else(More)
Collecting onsite received signal strength (RSS) is commonly employed in RSS-based positioning systems to achieve more accurate estimations. However, it requires a time-consuming site survey and a great amount of manual efforts. This study proposes a novel approach to reduce the need of massive RSS collection by quantifying the importance of each(More)
