To insure the quality and quantity of yields, computational tools for monitoring and analyzing the growth of crops are of great importance in scientific agriculture. In recent years, non-destructive measurements that utilize spectroscopy for crop monitoring have drawn much attention, and algorithms for selecting proper wavelengths are worth being investigated, since they have deep impact on the accuracy...
Modular multiplication is one of the most important operations in the public key cryptographic algorithms. In order to design a high-performance modular multiplier, we present a novel hybrid Montgomery modular multiplier over GF(p) on FPGAs, which employs Karatsuba and Knuth multiplication algorithms in different levels to implement large integer multiplication. A 9-stage pipeline full-word multiplier...
Sparse LU decomposition is the core computation in the direct method that solves sparse systems of linear equations. Only little work has been conducted on parallelizing it on FPGAs. In this paper, we study parallelization strategies for sparse LU decomposition on FPGAs. We first analyze how to parallelize the right-looking algorithm and find that this algorithm is not suitable for FPGAs. Then the...
A novel license plate positioning algorithm is proposed in this paper. The algorithm is composed of two parts, which are candidate region position and pseudo-region elimination. First the texture features are used to find candidate plates areas. Then a sliding strip window, which scans image from top to bottom, is used to select connectivity regions in the binary image of the candidate area. And pseudo-plate...
In this paper, we construct the cyclic block-type low-density parity-check (CB-LDPC) codes for low complexity hardware implementation. The CB-LDPC code, which is a special class of quasi-cyclic LDPC (QC-LDPC), has an efficient encoding algorithm due to the simple structure of their parity-check matrices. A distribution of irregular parity-check matrix for the CB-LDPC is developed so that we can obtain...
