Abstract: PROBLEM TO BE SOLVED: To efficiently simulate a system having a plurality of different types of ECU by software. SOLUTION: Each ECU emulator is speculatively emulated. That is, when the ECU emulator or each physical device simulator is called as a logical process, any critical path is not created, and each logical process is executed in parallel as much as possible, and even when any input event is not delivered in each logical process, the input is predicted, and the processing is advanced. This speculative execution makes it possible to previously execute processing without waiting for the output of another logical process so that the parallelism of processing can be increased. When the actual input to be received with delay is not matched with the predicted and speculatively executed input, it is determined that the speculative execution fails, and the status is returned to the previous time, and the processing is re-executed based on the actual input.

解决方案：每个ECU仿真器都被推测模拟。 也就是说，当ECU模拟器或每个物理设备模拟器被称为逻辑进程时，不会创建任何关键路径，并且每个逻辑进程尽可能并行地执行，并且即使当每个逻辑进程中的任何输入事件不在每个 逻辑过程，预测输入，并提前处理。 这种推测执行使得可以预先执行处理而不等待另一个逻辑进程的输出，使得可以增加处理的并行性。 当要延迟接收的实际输入与预测和推测执行的输入不匹配时，确定推测执行失败，并将状态返回到上一次，并根据实际情况重新执行处理 输入。 版权所有（C）2010，JPO＆INPIT

Abstract: PURPOSE: To enable a disk storage device used for video server, etc., to read out data at a high speed for reproducing compressed dynamic image data. CONSTITUTION: The storage disk 13 of a disk storage device stores I frames which are data-compressed in one frame so as to eliminate redundancy at storing positions from which the frames can be read out as continuously as possible. In addition, a sufficiently large capacity is given to the buffer of the disk storage device which temporarily stores data read-out from the disk 13. Therefore, only the readout of the I frames which are useful for high-speed reproduction becomes faster and, when the buffer has a capacity of two or more cylinders, the reading-out speed for ordinary reproduction does not become slower as compared with the conventional example.

Abstract: PURPOSE:To ensure the effective use of a storage and also to supply the data to a larger number of user terminal equipments. CONSTITUTION:The subcontrollers 241-24K successively read the unit data obtained by dividing and compressing the continuous animation image data out of the storages 261-26K according to the tokens stored in the queue of a system controller 14. Then the controller 14 supplies these unit data to the buffers 201-20M corresponding to the storages 261-26K respectively via a changeover switch 22 for connection corresponding to those tokens. The unit data stored in the buffers are supplied to the terminals 121-12M as the analog data on the animation images via the expanding devices 181-18M and D/A converters 161-16M. Therefore the unit data supplied from K pieces of storage are almost simultaneously given to K.N (=M) pieces of terminals.

Abstract: A user friendly interface is provided to a database system using real world modelling and card-like display representation wherein the format of the display representation enables the user to select and move directly to another such representation. As an example, the combination of a relational data base, a complex syntax language for processing it and apparatus handling the data base by executing in the language enables the user, within reason, to perform the macro-operations which he would do were he using the data base provided on a manual card system. The structure of the data base is comprised of two classes of entity, "complicate" accessible by name or via another such entity, and "basic" accessible only via a complicate entity. An entity is stored as format and data separately, these being combined in entirety for display purposes and, in appropriate part, for syntax generation, when required. The number of possible formats is limited so that full selection is a two step operation - first, the format and then the data - by name or by relational operation. Both local and relational operations can be performed and selection of the operation to be performed is by menu. If a relational operation is instructed, selection of a field in the format of the starting entity on the display automatically generates, within the apparatus, the appropriate syntax frame, which is filled with the parameters corresponding to that part of the data segment of the entity that is displayed in the field. If the instructed operation is local, the syntax is not generated. Additional operation parameters and data can be entered from a keyboard.

Abstract: PROBLEM TO BE SOLVED: To prevent the accumulation of the errors of values to be simulated in a simulation system.
SOLUTION: The simulation system is provided with a prediction module 710 for predicting a plurality of future values from the values of a plurality of input events in a logical process. The prediction module predicts the values of a plurality of future events from the values of a plurality of past events, and performs precedence speculation based on the predicted values of events until a new event is input. An error is generated between the plurality of newly predicted values of the events and the plurality of previously predicted values of events. The cumulative sum of the errors between the plurality of this time newly predicted values of events and the plurality of previously predicted values of events is calculated, and the number m of events whose cumulative sum falls into a prescribed threshold is calculated. The prediction module 10 rolls back the precedence speculation to time n+m within the range of the allowable error. The cumulative errors are distributed to a certain future point of time n+2m so as to be adjusted. Thus, it is possible to prevent errors from being accumulated.

Abstract: PROBLEM TO BE SOLVED: To read/write a value of a global variable speculatively and to enable rollback, in a simulation system by a computer. SOLUTION: For each global variable used in a logical process (LPn), writing of a value into a global variable is performed by writing write time and a write value thereof into a write table 1012, and reading of a value of a global variable is performed by reading of a value from the write table, and writing the time required therefor and a read value into a read table 1014. In response to writing performed into a global variable, in a simulation system, for an entry to a read table of each logical process, if an invalid entry is found in the read table by comparing entries in the write table, a doubt message is issued to a logical process related to the read table, and the logical process having received the doubt message performs necessary rollback processing.

Abstract: PROBLEM TO BE SOLVED: To efficiently simulate a system having a plurality of heterogeneous ECUs by software means. SOLUTION: Referring to an ECU emulator or each physical apparatus simulator as a logical process, each ECU emulator is speculatively emulated, and in each logical process, even if an input event is not reached, input is predicted to proceed with processing. By this speculative execution, processing is performed in advance without waiting for output of another logical process, thus improving parallelism in processes. If actual input received belatedly does not match with input for predicted speculative execution, the speculative execution ends in failure, thereby returning back to a state at the previous time, and on the basis of actual input, the processing is reexecuted. An allowable error is set for matching determination for actually received input and input at predictive speculative execution, thus enabling setting to satisfy both of accuracy and speed of simulation.

Abstract: PROBLEM TO BE SOLVED: To increase processing speed in a simulation system, such as full vehicle SILS (Software In the Loop Simulation). SOLUTION: A physical device simulator is normally continuously performed speculatively at high speed and, only when an actual input enters, a speculative input is compared with the actual input. In response to it that they do not match, the physical device simulator is returned to a point of time nearest to a point of time of the actual input, and a variable step is performed to the point of time of the actual input. When the point of time of the actual input is reached, high-speed continuous performance is returned to, so that processing speed of the simulator is considerably increased.

Abstract: PROBLEM TO BE SOLVED: To efficiently simulate a system having a plurality of different types of ECUs by software. SOLUTION: In this simulation system, respective ECU emulators #1 to #n are speculatively emulated. That is, the respective ECU emulators #1 to #n operate asynchronously with an individual clock and increment the original speculative period. Further, a system scheduler is provided to maintain all speculative periods sent by the respective ECU emulators, and the system scheduler updates the final time. When an ECU emulator receives an external input having a time stamp ahead of its own speculative period, the ECU emulator rewinds its own clock to the past time indicated by the time stamp and reexecutes a task. For this, the ECU emulator stores its own internal state, suitably in its own private memory at least for a certain fixed period. Consequently, the task can be reproduced by setting the internal state corresponding to the rewound time. COPYRIGHT: (C)2010,JPO&INPIT
