| 摘 要： | 针对原理性葛兰码计数器内在的竞争冒险问题,给出PLA 设计模型及简化方法,用PLA 模型设计了实用的葛兰码计数器。计数器电路仅用一片大规模集成电路GAL16V8 即可实现,彻底消除了静态冒险问题,并且实用可靠。同时给出的PLA 模型及其化简法对使用 LSIC 芯片进行数字系统的硬件逻辑设计有很好的参考价值。

| Abstract: | A static hazard problem inherent in principle ciruit of Gray-codccounter is analyzed and a new method for designing Gray-code counter by usingPLA model developed .The Gray-code counter can be implemented only by a chipof GAL16V8 LSIC with the help of a computer. The circuit of the new Gray-code counter has been proved stable and practical as a result of eliminatingthoroughly the static hazard in principle circuit. Moreover, the new methodis also valuable to logic hardwork design in digital system. |
