Abstract: We propose an input interface circuit that can provide input signals for the emerging all spin logic (ASL) devices. It consists of metal wires that are used for the transmission of electrical signals and magnetic tunnel junction that are used to transform electrical signals into input signals of ASL devices. The operation of input interface is validated by using a coupled spin-transport/magneto-dynamics model. A salient advantage of the proposed input interface is its ability to shorten the length of spin channel for spin transmission and avoid the complex fan-out structure when multiple identical input signals are needed. This input interface is especially useful for the design of large scale ASL circuits, in which many identical units are needed.

Abstract: This paper introduces the development of transmission design expert system base on MATLAB. It is discussed in detail that the establishment of expert system knowledge base， input and output (I/O) interface， material database and parameter database. In the part of the knowledge base, such as modeling of transmission design calculation, building of material database and parameter database are expounded detailedly. The I/O interface is built with MATLAB “Graphical User Interface (GUI)” technology, which is good at organizing knowledge, so ensure the consistency and rationality between I/O interface and knowledge base. Furthermore, the I/O interface makes the communication between the subsystems more convenience. Finally, with the help of expert system, a (4 + 1) gears Manual Transmission is designed, The result shows that the transmission expert system can shorten automobile transmission design calculating time and improve the calculation precision.
