在传统的计算机中，为了执行布尔逻辑函数，需要在晶体管之间布线。这导致处理器中数十亿个晶体管在物理上相互连接，这限制了集成密度，产生了巨大的功耗并限制了处理速度。因此，一种通过将布尔逻辑压缩到单个有源元件中来消除晶体管之间布线的方法是非常可取的。在这里，我们展示了一种新的逻辑架构，只使用一个机电参数谐振器，其中多个通道的二进制信息被编码为不同频率的机械振荡。参数谐振器可以混合这些通道，从而产生新的机械振荡状态，从而能够构建与、或和异或逻辑门以及多位逻辑电路。此外，机械逻辑门和电路可以同时执行，从而产生了在单个机械谐振器中并行逻辑处理器的前景。消除晶体管中的布线可能导致高集成密度和低功耗。在这里，通过参数混合与谐振器在不同频率的机械振荡相对应的二进制信息通道，在微机电谐振器中实现了多个逻辑门。
In conventional computers, wiring between transistors is required to enable the execution of Boolean logic functions. This has resulted in processors in which billions of transistors are physically interconnected, which limits integration densities, gives rise to huge power consumption and restricts processing speeds. A method to eliminate wiring amongst transistors by condensing Boolean logic into a single active element is thus highly desirable. Here, we demonstrate a novel logic architecture using only a single electromechanical parametric resonator into which multiple channels of binary information are encoded as mechanical oscillations at different frequencies. The parametric resonator can mix these channels, resulting in new mechanical oscillation states that enable the construction of AND, OR and XOR logic gates as well as multibit logic circuits. Moreover, the mechanical logic gates and circuits can be executed simultaneously, giving rise to the prospect of a parallel logic processor in just a single mechanical resonator. Eliminating wiring in transistors could lead to high integration densities and low power consumption. Here, multiple logic gates are implemented in a microelectromechanical resonator by parametrically mixing binary information channels corresponding to mechanical oscillations of the resonator at different frequencies.
