    摘要: An erasable programmable logic device (EPLD) includes function blocks connected by a universal interconnect matrix (UIM). The UIM includes both a cross-point circuit and a multiplexer-based (MUX-based) circuit. The cross-point circuit includes intersecting first and second conductors programmably connected by memory cells having control gates connected to the first conductors, drains connected to the second conductors, and sources connected to ground. The MUX-based circuit includes third and fourth conductors programmably connected by pass-gates having first terminals connected to the third conductors, second terminals connected to the fourth conductors, and gates connected to memory cells. The UIM further includes multiple-input multiplexers having first input lines connected to the cross-point circuit, second input lines connected to the MUX-based circuit, and output lines connected to the input lines of the function blocks. The multiple-input multiplexers are programmable to selectively apply signals from either the cross-point circuit or the MUX-based circuit to the function block input lines.

    摘要: A method of operating a pin of an in-system programmable logic device (ISPLD) which includes the steps of (1) applying a predetermined voltage to the pin when the ISPLD is in a set-up mode, and (2) maintaining the last voltage applied to the pin when the ISPLD is in a normal operating mode. The ISPLD is in the set-up mode when the logic of the ISPLD has not yet been configured, or is being configured. The ISPLD is in the normal operating mode after the logic of the ISPLD has been configured. A particular ISPLD includes a pin and a logic gate having a first input terminal coupled to the pin, a second input terminal coupled to receive a control signal, and an output terminal coupled to the pin. When the ISPLD is in the set-up mode, the control signal causes the logic gate to apply a predetermined voltage to the pin. When the ISPLD is in the normal operating mode, the control signal causes the logic gate to maintain the last applied voltage on the pin.

    摘要: A memory device, with increased storage speed and enhanced memory utilization, can be implemented by using multiplex clocking and efficient device design and enhanced flip-flop utilization. Transit time through the circuit, and hence circuit speed, can be controlled through multiplexed clock signals, and is increased by using fewer transistors in the signal path and allowing data to be transmitted directly to the flip-flop output by bypassing the flip-flop's master latch input.

    摘要: A complex programmable logic device (PLD) that includes a number of programmable function blocks and an instruction bus for receiving programming instructions. The programming instructions are used to program the function blocks to enable the PLD to perform one or more desired logic functions. The PLD also includes an instruction-blocking circuit that is connected to each of the functional blocks. When directed by a user, the instruction blocking circuit selectively blocks programming instructions on the instruction bus from one or more of the function blocks while allowing the other function blocks to receive the programming instructions. Thus, one or more function blocks in the PLD are reprogrammed without interrupting the operation of the remaining function blocks.
