A Novel Parallel Hardware Methodology for Solving Linear System of Equations
In this paper, we proposed a parallel hardware methodology employing the modified Gaussian elimination algorithm to efficiently solve linear system of equations (LSEs). Two parallel operators are issued in the hardware-optimized algorithm. Moreover, to be the proof-of-concept, the proposed parallel methodology is implemented to hardware structures in cases to address solving LSEs over GF (2) (primarily are bits-operation) and LSEs with floating-point (IEEE-754 standard, 32-bit single precision) coefficient matrix. The corresponding hardware is mainly composed of uniformly distributed basic cells which store and register data, yielding a standalone worst ? case time complexity O(n2) opposed to O(n3) of the software replication. Finally, the given experimental result inosculated with the theory analysis.
