This paper designs a link layer controller for a serial bus that based on the IEEE 1394 standard. The design is compatible with the interface of physical-layer chips, and able to work at up to 400Mbps in asynchronous transmission mode. Fig. 1 shows the structure of the controller. Based on the analysis of the function of PHY-interface, Fig. 3 shows the(More)
Small particle’s manipulation is one of the important problems in micro-technology. It has many advantages to apply AC electric field for the manipulation of small particles. With the using of forces generated by an electric field, it is possible to create very compact devices for the particle handling. Since no moving machine parts are involved, it could(More)
Step-Motor is a kind of important drive element in automatic control of machines (NC machine tools etc.). Many researchers have pointed out that the audio card could be applied in many fields such as data acquisition, motor control etc. Its advantages : no driving program needed to write, good compatibility with operation system and no update problem of the(More)
