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.

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 data transmitting apparatus for transmitting data to a plurality of data receiving apparatuses comprises acquiring means, organizing means, and transmitting means. The acquiring means acquires a plurality of sets of selection data, each set of which is targeted for one data receiving apparatus model. The organizing means compares the plurality of sets of selection data and extracts common data and unique data. The common data is a portion of one set of selection data that is also contained in one or more other sets of selection data, and the unique data is a remaining portion in each set of selection data left after excluding the common data. The transmitting means transmits the common data and the unique data together to the plurality of data receiving apparatuses.

摘要： In this system, program data is generated by configuring a plurality of modules based on a relationship between dependence of the modules composing the program. Then, generated two versions of program data is compared starting from a head address of each of the program data, and data at an address, and thereafter, where the data first makes a difference is extracted to generate difference data. Further, a center holds the latest version of program and at least one item of difference data, and transmits the whole data of program or difference data corresponding to a program version in a terminal apparatus, and the program is updated in the terminal apparatus using the received data.

摘要： An arithmetic unit includes a switching device 16 and a cache controller 19. The switching device 16 determines whether desired data to be read by the CPU 11 is in a RAM 14, and allows, depending on a result of the determination, the CPU 11 to directly read the desired data from a ROM 13. The cache controller 19 controls a cache 12 so that the RAM 14 is initialized based on cache data corresponding to the desired data stored in the cache 12. In an arithmetic unit having a CPU, a cache, RAM, and ROM configured in the above manner, the time required for a startup process is reduced.
