For special structured linear systems, WZ factorizations of matrices are basic mathematical theories to design a class of parallel solving algorithms. So, firstly, new WZ factorizations for the p-tridiagonal matrix are proposed and proved. Next, an effective parallel algorithm is designed. Solving both the subsystem in each processor and the reduced subsystem makes use of the WZ factorization so that...
For linear systems with coefficient matrices of classical structure, WZ factorizations for matrices are basic mathematical theories to design a class of parallel algorithms. Based on WZ factorization, a parallel algorithm is provided for symmetric tridiagonal linear systems. The method estimates the computation task carefully so that it assigns the system skillfully to get even load balance. In addition,...
Embedded systems have been used in industry control field widely for its excellent advantages of small space, powerful performance, high reliability, low power dissipation and special purpose. In this paper, we designed an embedded ARM hardware circuit using the microprocessor S3C44B0 as a core according to a testing principle of wiring harness. Its interface circuit can be used for controlling and...
