    • A fracturable logic element includes a first, second, third, and fourth two-input lookup tables (2-LUTs). Each 2-LUT includes four memory elements. Each memory element is configured to hold one data bit. The fracturable logic element also includes a set of six inputs and a control circuit configured to operate in a first mode and a second mode. When the control circuit operates in the first mode, a first combinatorial output is generated using four of the set of six inputs and the first, second, third, and fourth 2-LUTs. When the control circuit operates in the second mode, a second combinatorial output is generated using a first subset of three of the set of six inputs and the first and second 2-LUTS. Additionally, when the control circuit operates in the second mode, a third combinatorial output is generated using a second subset of three of the set of six inputs and the third and fourth 2-LUTs, the first and second subsets being non-intersecting subsets of the set of six inputs.
    • 可分解逻辑元件包括第一,第二,第三和第四双输入查找表(2-LUT)。 每个2-LUT包括四个存储元件。 每个存储器元件被配置为保持一个数据位。 可分解逻辑元件还包括一组六个输入和被配置为在第一模式和第二模式下操作的控制电路。 当控制电路在第一模式下工作时,使用六个输入和第一,第二,第三和第四2-LUT中的四个产生第一组合输出。 当控制电路在第二模式下操作时,使用该组六个输入和第一和第二2-LUTS中的三个的第一子集来生成第二组合输出。 另外,当控制电路在第二模式下工作时,使用六组输入和第三和第四2-LUT组中的三个的第二子集来产生第三组合输出,第一和第二子集是不相交的子集 一组六个输入。

    • A logic element includes memory elements, multiplexers, and controls. The multiplexers are arranged in levels including a highest level of multiplexers with inputs connected to the memory elements and outputs connected to inputs of a next-to-highest level of multiplexers and a first level of multiplexers with inputs connected to outputs of a second level of multiplexers and at least one output. The controls are connected to the multiplexers. In a first operational mode the controls determine a first-mode output at the at least one output of the first level of multiplexers, and in a second operational mode the controls determine a plurality of second-mode outputs at selected outputs of multiplexers not at the first level of multiplexers.
