Programmable logic array

摘要

Given a programmable logic array, all product terms of the product matrix are applied to a prescribable potential by way of a first control signal so that the following sum matrix is no longer influenced by the input variables. Additional transfer elements are controllable by a second control signal, the additional transfer elements being assigned to additional terminal connecting points between the sum terms of the sum matrix. Depending upon the execution and employment of the logic array, the two control signals can be independent of one another, identical to one another, or inverted relative to one another.
