摘要： To start up an operating system (OS), CPU performs initializations in three modes: The three modes include a first I/O initialization (Early init) (132) which is to be done serially when no threads are yet usable, without any advanced technique and with a long wait time until a next operation can be made; a second I/O initialization (136) which is to be done when threads are usable, in a plurality of steps parallelized with each other using the usable threads according to the dependency relation between devices to be initialized and with synchronization between the steps each by a barrier; and a third I/O initialization (Lazy init) (140) in which remaining initializations are done in parallel with each other using the threads commensurately to a user process when the user process becomes executable. The present invention is applicable to home-use electric or electronic appliances.

摘要： A process scheduling apparatus has a delayed task handling process for processing delayed tasks having variable priorities and multiple other processes for handling processes other than delayed tasks. Fixed priorities are assigned to the other processes. The process scheduler sequentially executes the delayed task handling process and the other processes according the assigned priorities. A delayed task registration processor stores newly generated delayed tasks with assigned priorities in a queuing table. A delayed task priority controller selects the delayed task with the highest priority in the queuing table. A process priority controller sets the priority of the delayed task handling process to the same priority as the priority of the delayed task with the highest priority.
