Patent number: 8676560Abstract: In a normal operation, a physical unit simulator is allowed to speculatively perform high-speed continuous execution. Only when an actual input comes in, a speculative input and the actual input are compared with each other. Thereafter, in response to inconsistency between the inputs, the physical unit simulator is returned to a point closest to the point of the actual input and is allowed to execute a variable step module to reach the point of the actual input. Upon arrival at the point of the actual input, the simulator is shifted back to the high-speed continuous execution from there. Thus, a processing speed of the simulator can be significantly improved.Type: GrantFiled: June 9, 2009Date of Patent: March 18, 2014Assignee: International Business Machines CorporationInventors: Koichi Kajitani, Hideaki Komatsu, Shuichi Shimizu

Patent number: 8670967Abstract: A simulation system, method, and article of manufacture. A simulation system has a discrete and a continuous portion. The discrete portion further has a peripheral emulator in communication with the continuous portion of the simulation system. A portion of a peripheral emulator is separated and is caused to operate in a thread of a continuous system. The continuous system and the peripheral are in loose synchronization and therefore sparsely communicate with each other. The configuration significantly reduces the frequency of inter-thread communications between the continuous system and the discrete system that are performed in response to a continuous clock in a simulation system including the continuous system and the discrete system, thereby reducing communication cost. Accordingly, the operation speed of the simulation system can be increased.Type: GrantFiled: March 10, 2010Date of Patent: March 11, 2014Assignee: International Business Machines CorporationInventors: Hideaki Komatsu, Fimitomo Ohsawa, Shuichi Shimizu

Publication number: 20130151220Abstract: A method and system where a plurality of ECU is rapidly executed while avoiding deadlock by performing conservative event synchronization. The simulation system is provided with 4 layers, namely a processor emulator which is an ECU emulator, a plant simulator, a external peripheral scheduler, and a mutual peripheral scheduler. The external peripheral scheduler performs advanced execution of the plant simulator only during processor emulator reaction delay time (or the time until the next event). The notification to perform advanced execution of the processor emulator is provided until the actual plant simulator stop time. The mutual peripheral scheduler provides notification to the processor emulator to perform advanced execution only during communication delay timing between processor emulators (or the time until the next event). The processor emulator conservatively processes until the earliest time of the notification times.Type: ApplicationFiled: July 27, 2011Publication date: June 13, 2013Applicant: International Business Machines CorporationsInventors: Ikuo Matsumura, Shuichi Shimizu

Patent number: 8406311Abstract: A method and system for embedding an electronic watermark directly in an MPEG stream is provided. An intra-macroblock of an I-frame or of a P or B-frame is detected in an MPEG stream, and following the detection of an intra-macroblock of the I-frame or of the P or B-frame, data for one macroblock are extracted from the MPEG stream and buffered. An embedding pattern is embedded in the buffered macroblock without changing the length of VLC, and the resultant macroblock is returned to the MPEG stream. More specifically, a DC factor is extracted from the buffered macroblock, and a pseudorandom number is generated to produce an embedding pattern. Then, whether the bit length of the DC factor will not be changed by embedding the obtained embedded pattern is determined. When the bit length of the DC factor not be changed, the embedding pattern is embedded in the buffered macroblock. When the bit length will be changed, whether ½ of the embedding pattern can be embedded is determined.Type: GrantFiled: October 31, 2007Date of Patent: March 26, 2013Assignee: International Business Machines CorporationInventors: Koichi Kamijo, Shuichi Shimizu, Norishige Morimoto

Patent number: 8271587Abstract: An object movement control system, an object movement control method, a server, and a computer program that can update the positional information of an object in a virtual space at high speed by appropriately distributing processing loads. Client control units obtain information about the position of a first object in a virtual space and information about movement of the first object and detect other objects that exist in a virtual region that contains the first object, which has been moved. The distances between objects that exist in a virtual region are calculated, and only when the number of objects the distances to which are shorter than a predetermined threshold exceeds a predetermined number, information about the objects is sent to a server. The server assigns a collision determination client that performs collision determination to each pair of objects selected from the objects.Type: GrantFiled: March 20, 2009Date of Patent: September 18, 2012Assignee: International Business Machines CorporationInventors: Kazuaki Ishizaki, Shuichi Shimizu

Patent number: 8219997Abstract: To implement job execution in which resource assignment and change of the assignment can be dynamically and autonomously performed so as to meet requirements of a job in a job and resource environment in which the operational status cannot be forecasted in advance. A job that can be divided into a selected number of tasks is provided to one computer of a plurality of computers connected via networks, and job tasks are processed with the one computer for predetermined time. A progress rate of task processing for the predetermined time is calculated, and completion time for task processing on the one computer is estimated on the basis of the progress rate and the predetermined time. It is determined whether the estimated completion time meets requirements of the job. When the estimated completion time meets the requirements, job tasks are processed with the one computer, and results are generated.Type: GrantFiled: November 1, 2007Date of Patent: July 10, 2012Assignee: International Business Machines CorporationInventors: Shuichi Shimizu, Toshiyuki Yamane
