The power of programmability gives industrial automation designers a highly efficient, cost-effective alternative to traditional motor control units (MCUs)。 The parallel-processing power, fast computational speeds, and connectivity versatility of Xilinx® FPGAs can accelerate the implementation of advanced motor control algorithms such as Field Oriented Control (FOC)。
Additionally, Xilinx devices lower costs with greater on-chip integration of system components and shorten latencies with high-performance digital signal processing (DSP) that can tackle compute-intensive functions such as PID Controller, Clark/Park transforms, and Space Vector PWM.
The Xilinx Spartan®-6 FPGA Motor Control Development Kit gives designers an ideal starting point for evaluating time-saving, proven, motor-control reference designs. The kit also shortens the process of developing custom control capabilities, with integrated peripheral functions (Ethernet, PowerLink, and PCI® Express), a motor-control FPGA mezzanine card (FMC) with built-in Texas Instruments motor drivers and high-precision Delta-Sigma modulators, and prototyping support for evaluating alternative front-end circuitry.
在集成電路內建自測試的過程中,電路的測試功耗通常顯著高于正常模式產生的功耗,因此低功耗內建自測試技術已成為當前的一個研究熱點。為了減少被測電路內部節點的開關翻轉活動率,研究了一種隨機單輸入跳變(Random Single Input Change,RSIC)測試向量生成器的設計方案,利用VHDL語言描述了內建自測試結構中的測試向量生成模塊,進行了計算機模擬仿真并用FPGA(EP1C6Q240C8)加以硬件實現。實驗結果證實了這種內建自測試原理電路的正確性和有效性。
