A raster-imaging processing (RIP) time is predicted for each of a number of pages to be printed in printed-page number order. The pages are sorted based at least on when RIP should be finished for each page. The pages are dispatched to RIP components for RIP at least substantially in an order in which the pages have been sorted. Each page is dispatched to a next RIP component that is available. A RIP component is available for a given page to be dispatched thereto where a total size of the RIP component's output buffer minus space within this output buffer taken up by any pages ordered after the given page in the printed-page number order is greater than the needed space to store the given page. The pages as have been raster-image processed are retrieved from the output buffers in the printed-page number order and transmitted to a printing device.

For communication between a display device and a processing apparatus (host), two connection modes are prepared, a wired connection mode, for communication along a wired connection path, and a wireless connection mode, for communication along a wireless connection path. Before entering the wireless connection mode, the processing apparatus (host) transmits, along the wired connection path to the display device, data required for the wireless connection of the display devicealong the wireless connection path, and data required for authentication to permit information to be accessed using the wireless connection path.

A system and method which dynamically changes the load balance of assigned loads for each group in a sequence of processes from a first stage to an n-th stage in a computer having a plurality of processors, wherein the plurality of processors are grouped into at least two groups, comprises the steps of: detecting a change in a characteristic value in a queue for transferring a processing result between the groups; and changing the assignment of assigned processes for each group based on the change in the characteristic value. A characteristic value stored in a queue represents a value related to work load, and a queue seldom becomes full or empty if the load balance is changed referring to this characteristic value.

The present invention enables image information of high resolution to be transferred via a transmission line with limited band width using a simple configuration. In transferring image information between a main body of a computer and a display, a dither matrix is used to update images stored in the display. That is, a plurality of blocks whose size is of a predetermined dither matrix are defined in an image, and information of each pixel in each block is transferred to the display in order of a value of a corresponding element in the dither matrix. Transfer of unchanged pixel data can be omitted. In addition, in transferring image information between the main body of the computer and the display, image information stored in the computer is divided into a plurality of blocks, for each of which the number of changed pixels or the number of writings to pixels in the block is calculated so that image information in blocks which exceed a predetermined number is transferred to the display block by block.

Data sets of sequential data strings at a particular point in time are assigned to processing elements of a multiprocessor system at high speed and processing is executed efficiently in parallel. A mechanism for preventing allocation due to all-read to a cache block which has not yet been referred from another cache is added by providing a reference bit with respect to cache blocks. The reference bit becomes 0 when new data is read to the cache block and becomes 1 when the cache block is referenced by a CPU. In the case of reading data from another cache, if a block corresponding thereto can be replaced without the need to be written back to the other cache and the reference bit is 1, data is fetched to the shared cache memory.

A mobile machine having active sensors for allowing similar energy waves to coexist close to each other. A mobile machine enters an exclusive transmission mode with respect to energy wave transmission when interference can occur between its own active sensor and the sensors of mother mobile machines. Prior to the transmission of energy waves, the mobile machine determines whether or not any competing mobile machine has acquired the energy wave transmission right. If not, it broadcasts a declaration of its acquisition of the right to transmit energy waves and transmits energy waves. If the transmission right has already been acquired by a competing mobile machine, it adds its own identification to a transmission queue, and increments the transmission queue each time it receives a declaration of renunciation of the right to transmit energy waves from a competing mobile machine.
