摘要： Before starting data transfer, the sender node sends the CONNECT message requesting security of hardware resources necessary for data transfer to the receiver node. Each node relaying the CONNECT message secures the CPU time and bandwidth necessary for data transfer and sends the CONNECT message to the receiver node. Upon receipt of the CONNECT message, the receiver node reserves the CPU time necessary for data reception and then sends the ACCEPT command to the sender node. The sender node receives the ACCEPT command and then sends a data packet.

摘要： A process executing method capable of performing multiprocessing by using a shared resource without impairing periodical drivability of processes designed for executing continuous media processing. When a process requests the use of the shared resource, abortion of that process is first disabled by the process itself by using an abort disable function and then preemption of the same process is disabled by means of a preempt control module, whereupon the process enters a processing executed by using the shared resource. Upon completion of the processing for the shared resource, the process is immediately set to a preempt-enabled state by means of a preempt control module. After completion of all the processings, the abort-disabled state is finally cleared by using a disabled-abort clear function. Upon occurrence of forcive termination of a process in the abort-disabled state thereof, execution of this process is continued until the abort-disabled state is cleared, and the process is terminated forcibly after the abort-disabled state has been cleared.

摘要： A scheduling method of a periodic process of a computer system for keeping the execution interval of each process group constant as far as possible in the case where a plurality of process groups including periodically executed processes are executed in parallel. If a group master process of each process group specifies a wakeup interval period and a required CPU time per period and requests allocation of a CPU time, then a CPU allocation time of a specified process group is secured so as not to collide with a CPU allocation time of another process group, and a scheduling table is created so as to maintain the specified wakeup interval period. In response to arrival of time when one of the process groups should be waked up, a kernel process or a scheduler conducts wakeup by changing execution priority of a process belonging to this process group to highest priority ("raised") in the system, and thereafter maintains the highest priority for CPU allocation time consecutively allocated.

摘要： A method of transferring multimedia data from an input device to an output device in a computer system having a plurality of input/output devices. An application program specifies an origination and destination of multimedia data transfer and orders multimedia data transfer start. A periodic driven program conducts multimedia data transfer in accordance with the order given by the application program. The application program can conduct other processing irrespective of the multimedia transfer state after giving the transfer start order. The periodic driven program operates with a predetermined period, divides multimedia data, and transfers the multimedia data in a plurality of periods.
