摘要:
A programmable integrated circuit with lookup table circuitry is provided. The lookup table (LUT) circuitry may be formed using multiplexers. A multiplexer in the lookup table circuitry may be implemented using only tristate inverting circuits. Each tristate inverting circuit may include a first set of n-channel and p-channel transistors that receive a static control bit from a memory element and a second set of n-channel and p-channel transistors that receive true and complementary versions of a user signal. The first and second sets of transistors may be coupled in series between a positive power supply terminal and a ground power supply terminal. A LUT multiplexer implemented in this way need not include separate transmission gates at the output of each tristate inverting circuit and may exhibit minimal subthreshold leakage.
摘要(中):
提供具有查找表电路的可编程集成电路。 查找表(LUT)电路可以使用多路复用器形成。 查找表电路中的多路复用器可以仅使用三态反相电路来实现。 每个三态反相电路可以包括从存储器元件接收静态控制位的第一组n沟道和p沟道晶体管以及接收用户的真实和互补版本的第二组n沟道和p沟道晶体管 信号。 第一和第二组晶体管可以串联耦合在正电源端子和地电源端子之间。 以这种方式实现的LUT多路复用器在每个三态反相电路的输出端不需要包括单独的传输门,并且可以表现出最小的亚阈值泄漏。 p>
