查询词典 unit

On the basis of kinematic analysis of beam pumping unit,the general dynamics equation in the form of virtual power was applied to analyze the contribution of every part including balancing weight of a beam pumping unit to crank axle torque in consideration of inertia effects. The exact analytical expression for computing crank axle torque was obtained.

By simulating the switch unit, it can be seen that ATM switch unit that is designed by use of hierarchical design of top down with VHDL can perform the basic function of cell head changing, routing and queuing. If many cells race one output channel, the ATM switch can put these cells into a buffer, then queue and output them. When the broadcast cell advents, it can be delivered to all channels.

本文通过对所设计的基于VHDL描述的ATM交换单元进行仿真验证可以得出如下结论：采用自顶向下的层次化设计、由VHDL描述的ATM交换单元能够实现信头变换、选路和排队三项基本功能；当多个信元同时竞争某一出端时能够对信元进行缓冲存储和排队输出；而且当有广播信元到来时还可以对所有出端进行广播输出。
