Chinese Abstract

在運用同倫算法進行逆變器PWM消諧方程實時求解過程中,矩陣求逆是關鍵。通過對上三角矩陣求逆算法的研究,提出了一種適合ASIC實現的基於二維心動陣列的矩陣求逆並行結構。運用硬件描述語言(VHDL)對其建模,並通過Synopsys的Design Compile綜合和Cadence的 NC-Sim對其進行綜合後仿真。仿真結果表明,該並行結構能夠在2n+1個時鐘週期內完成n階矩陣求逆,而傳統的串列計算至少需要n^3個時鐘週期。

English Abstract

The inverse matrix calculation is the key to solve harmonic elimination PWM model of inverter based on Homotopy algorithm. In light of the analysis of the algorithm of up-triangle matrix's inverse, a two-dimension systolic array structure for ASIC implementation is introduced. The structure is modeled by VHDL, synthesized by Design Compiler of Synopsys and simulated by NC-SIM of Cadence. The result shows this parallel structure can finish n-order matrix inverse calculation in 2n+1 clocks, but traditional serial computation needs n^3 locks.
