    摘要: A programmable logic array (PLA) in accordance with the invention achieves a maximum amount of depopulation of programmable connections while sill implementing a logic function and maintaining flexibility for future reprogramming. In addition, a PLA in accordance with the invention can be built so that no matter what functionality is programmed, performance characteristics for the device are maintained. Further, a PLA in accordance with the invention does not require a regular array structure.

    摘要: A PLD comprises a programmable first AND array whose inputs are selectively connectable to input lines and whose outputs are selectively connectable to a programmable second OR array. The PLD further comprises a programmable third AND array whose inputs are selectively connectable to the input lines, and whose outputs are fixedly connected to inputs of a fixed fourth OR array. The outputs from the second OR array are also connected in a fixed manner to the fourth OR array. This arrangement overcomes some of the weaknesses in both the conventional PAL and PLA architectures while retaining most of their strengths.

    摘要: A programmable logic device that provides an AND gate array connected to an OR gate array connected to a third logic level, a logic expander module (121, 123). The module provides programmable selection of any of 16 one- and two-variable logic functions or any of 256 one-, two- and three-variable logic functions. In one embodiment (11, 61), the invention uses logic function gates such as AND, OR, XOR and inverter gates to form the logic functions. In a second embodiment (91) and a third embodiment, a look-up table and an array of pass transistors, respectively, are used to form the logic functions.

    摘要: A novel ECL Programmable Logic Array (PLA) is provided which operates as an ECL PLA, having ECL voltage level compatible input and output leads, thereby providing a high-speed PLA. A unique programming means is provided which allows the ECL PLA to be programmed using TTL-compatible programming voltage levels, such as are provided by common and inexpensive prior art TTL PLA programmers. In another embodiment higher speed is achieved by the design of each sense amplifier using emitter function logic such that the sense transistor and load functions a cascode amplifier. In another embodiment a lower power PLA device is achieved by utilizing a switched current source pull down means for pulling down the rows of the PLA array. In another embodiment low power and user convenience is achieved by allowing each pair of output terminals to share a predefined set of product terms. In another embodiment of this invention, each output terminal is capable of having its output polarity programmed, in order to provide either a desired product term, or the inverse of that product term.
