Multi-exponentiation is very important in varies cryptographic and digital signatures. In the situation like electronic cash and SNS websites, the server need to answer a mass of requests in a short time. With every request, there are always processes of encryption, decryption, signature and verification. In these processes, there are large amount of computations of multi-exponentiation, which shows...
In many-core based parallel computing field, how to optimally allocate and schedule computing core resources according to characteristics of parallel applications is one typical and fundamental problem, which touches closely to computing performances. After analyzing features and mechanisms of Kepler CUDA architecture, three heterogeneous streaming parallel computing modes and corresponding constraints,...
This paper presents a multi-functional double precision floating-point multiplier design. The proposed design can perform one double precision multiplication or one vector multiplication of two 2D vectors which is consist of single precision floating-point numbers. The proposed design is modeled in Verilog-HDL and verified through extensive functional simulation. The presented multi-functional double-precision...
A power-efficient K-Means hardware architecture that can automatically estimate the number of clusters in the clustering process is proposed. The contributions of this work include two main aspects. The first is the integration of the hierarchical data sampling in the hardware to accelerate the clustering speed. The second is the development of the “Bayesian-Information-Criterion (BIC) Processor”...
Partial evaluation is an automatic approach to customize a program with respect to configuration values and invariants of the program itself. XQuery is a new query language for querying XML data source. In this paper, we present a partial evaluation system for the XQuery language named XQPE. XQPE is an off-line partial evaluation system; it offers specialization at compile time, and program specialization...
