摘要

介绍了一种利用电荷耦合器件(CCD)技术实现多值多阈值(MVMT)功能的新型可编程逻辑阵列(PLA)。结果表明，使用所提出的结构实现的功能数量大于使用作者先前报道的PLA结构实现的功能数量。例如，所有256个四值三阈值函数可以仅使用拟议PLA的一列合成，而如果使用现有结构则需要两列。这种功能的增加是通过将每列的门数从8增加到12来实现的。通过控制所使用的门的阈值，新结构显示了在用户级动态可编程的理想特性。给出了一个合成程序，该程序可用于合成MVMT函数，以便使用所提出的PLA实现。

On the synthesis of MVMT functions for PLA implementation using CCDs

A new programmable logic array (PLA) for implementation of multivalued multithreshold (MVMT) functions using charge-coupled-device (CCD) technology is introduced. It is shown that the number of functions realized using the proposed structure is larger than those realized using the authors' previously reported PLA structure. For example, all 256 four-valued three-threshold functions can be synthesized using only one column of the proposed PLA, as compared with two columns if the existing structure is used. This increase in functionality is achieved through increasing the number of gates per column from 8 to 12. The new structure exhibits the desirable feature of being dynamically reprogrammable at the user level by controlling the thresholds of the gates used. A synthesis procedure which can be used to synthesize MVMT functions for implementation using the proposed PLA is given.<>
