Abstract
A microprocessor with a hierarchical PLA control arrangement with a relatively rich function capability is achieved by applying the same subsection of the bit field of the output register of a control PLA to the inputs of each of the controlled PLA's. In addition, routing bits in the output register of the control PLA are applied to gate the clocks at the inputs of the controlled PLA's. Significant increase in PLA function, relative to PLA size, is achieved.
