    摘要： The present invention is a command or data transfer between two integrated circuit devices (hereafter LSIs) wherein an LSI issuing a command or data (issuing side LSI) outputs a strobe signal, which indicates that a valid command or data was transmitted, to the LSI which receives the command or data (receiving side LSI), and the receiving side LSI outputs a signal, which notifies that the command processing completed (command ready signal), to the issuing side LSI. The issuing side LSI comprises a counter where a value to indicate the number of commands which the receiving side LSI can simultaneously process or simultaneously receive is loaded at initialization, wherein the counter is decremented when a command or data is issued, the counter is incremented when the ready signal is received, and issuing a command or data is inhibited when the counter becomes “0”. Therefore the issuing side LSI can issue a command or data to the receiving side LSI without confirming a busy signal from the receiving side LSI.

    摘要： In a processor, an operating unit executes an instruction within an instruction set, and a second operating unit executes other custom instructions. The second operating unit consists of a plurality of AND circuits, OR circuits, adders, selectors, and multiplexers. The information about which circuit should be combined with which circuit when the instruction is input is held in advance as structure information in a configuration memory. One piece of structure information corresponds to one custom instruction. The second operating unit in an optimum circuit structure determined based on this structure information executes the instruction. With this arrangement, it is possible to increase the processing speed than when the operating unit executes the processing.

    摘要： A flexible magnetic disk drive is disclosed which has a stepper motor coupled to a data transducer via a steel belt motion translating mechanism for moving the transducer from track to track on the rotating disk in response to stepping pulses and a stepping direction signal from an external host system. In order to save power, the stepper motor is held deenergized while the disk drive motor is out of rotation, with the consequent possibility that the transducer may be displaced from the required track position on the disk while the stepper motor is held deenergized. Therefore, in order to always memorize the latest of the successive destination tracks commanded by the host system, a forward/backward counter is provided which counts the external stepping pulses in either direction depending upon the binary state of the external stepping direction signal. After the disk drive motor is set into rotation, stepping pulses and an stepping direction signal are generated internally for causing the stepper motor to automatically reposition the transducer on the memorized latest destination track.
