介绍了基于ALTERA 公司FPGA 的双NIOSII 软核处理器在化工设备——脱丁烷塔控制系统中的应用。由于双CPU 处在同一块FPGA 芯片中，并且分担了不同的控制环节，使得整个控制系统与同功能类型产品相比，在成本显著降低的同时，安全性和抗扰动能力大幅提升-ALTERA FPGA-based company introduced a dual-core processor NIOSII soft Chemical Equipment- De-butane tower control system. As the pair of CPU chip in with an FPGA, and share the control of different areas, makes the whole control system and compared to the same types of functions, the cost is significantly reduced, the security and disturbance rejection capabilities significantly Tisheng
