    摘要： A programmable logic device having a relatively small number of programmable product terms (0E,SETN,INV,P0,P1,P2,ACLK,CLEARN) ("P-terms") feeding each fixed combinatorial logic device (51), and additional "expander" programmable P-terms (EXP1,EXP2) which do not directly feed a fixed device. Relatively simple logic functions can be performed by suitably programming the P-terms feeding the fixed devices. More complex logic functions can be performed by suitably programming the required number of expander P-terms, and then combining the outputs of those P-terms by means of another P-term. In order to conserve word lines in the programmable array, multi­plexers (150) allow selection of whether expander outputs or external inputs (44) will be applied to certain word lines (102).

    摘要翻译： 一种可编程逻辑器件，其具有相对较少数量的可编程产品项（0E，SETN，INV，P0，P1，P2，ACLK，CLEARN）（“P项”），馈送每个固定的组合逻辑器件（51） 扩展器“可编程P项（EXP1，EXP2），不直接馈送固定设备。 可以通过对馈送固定设备的P项进行适当编程来执行相对简单的逻辑功能。 可以通过适当地编程所需数量的扩展器P-项来执行更复杂的逻辑功能，然后通过另一个P项组合这些P项的输出。 为了节省可编程阵列中的字线，多路复用器（150）允许选择扩展器输出或外部输入（44）是否将被施加到某些字线（102）。
