A processor includes a CPU core which executes a user program, and a data transfer apparatus. The CPU core stores a transfer request from a user program in a specific area of a main memory, in which the transfer request specifies the virtual addresses of a transfer source and a transfer destination in a memory space allocated to the user program. The data transfer apparatus refers to the specific area of the main memory and acquires a transfer request asynchronously to processing performed by the CPU core. The data transfer apparatus then identifies physical addresses corresponding to virtual addresses specified in the transfer request. After that, the data transfer apparatus transcribes original data stored in a storage area indicated by the physical address of the transfer source, to a storage area in a cache memory related to the virtual address or physical address of the transfer destination.

Data transfer apparatus, data transfer method and processor

A sub-processor different from the main processor executing control in the operating system (OS) is designated to control a device driver corresponding to a communication unit and thus, the communication control is executed by the sub-processor in response to an interrupt originating from a network card functioning as the communication unit in an information processing apparatus equipped with a plurality of processors and engaged in communication via a network. The structure enables the main processor to execute data processing with a high level of efficiency without a time lag in the data processing.

This invention is a digital still camera having a coded data quantity monitoring circuit (). This monitoring circuit () detects the quantity of data of an image signal compressed by a JPEG compression circuit (). When a CPU () judges that the quantity of data detected by the coded data quantity monitoring circuit () is equal to or more than a maximum coded data quantity S, first, an image pickup element () is caused to pick up an image of an object again and output a different image signal, and a quantization table to be used in a quantization circuit () is changed. Next, the different image data is compressed by being DCT-transformed by a DCT circuit (), then quantized by the quantization circuit () and coded by a coding circuit (). The compressed different image signal is recorded to a memory card (). In this case, the different image signal is recorded into an area where an image signal has been recorded in advance on the memory card ().

Digital broadcast reception apparatus and picture printing method

In a printing system in which with a plurality of different types of controllers connected to one serial bus, different types of print data can be inputted to and printed by a printing unit. When a set top box and desktop and portable personal computers, different in type from each other, are connected to a IEEE 1394 serial bus, screen data is outputted from the set top box to an AV/C printer and PDL data is outputted from the personal computers to the AV/C printer. The AV/C printer judges the image type of the input data. Based on the image type, the printing system converts the print data to a type of print data supported by the AV/C printer.
