摘要： A semiconductor device includes a plurality of IP cores, a plurality of storage devices, a configuration information acquiring unit that acquires configuration information for specifying a timing when the IP core accesses the storage device, and an allocation determining unit that determines the storage device allocated to the IP core. The configuration information acquiring unit acquires configuration information regarding a first IP core and configuration information regarding a second IP core. The allocation determining unit determines, based on the configuration information, whether an access timing by the first IP core is the same as an access timing by the second IP core, and when it is determined that the access timings are the same, determines allocation in such a way that the storage device allocated to the first IP core becomes different from the storage device allocated to the second IP core.

摘要： The present invention is directed to reduce deterioration in parallel processing capability. In a moving-picture decoding processing apparatus, information of a first plurality of frames and a second plurality of frames is supplied from a decoding control unit to first and second decoding processing units. For decoding the information from an intermediate point to an end point of a second preceding frame by the second decoding unit in a third period, use of a result of the process of the first decoding processing unit in the third period is inhibited, and use of a result of the process of a first preceding frame by the first decoding processing unit in a second period is permitted by an end signal. By reach of the intermediate point of the decoding of the second preceding frame by the second decoding processing unit in the second period, information from the start point to the intermediate point of the first subsequent frame included in the plural frames is decoded by the first decoding unit in the third period.

摘要： To improve an image recognition rate by quickly changing a parameter in a proper manner without being affected by a transmission delay of an image encoding stream in an image receiving device that recognizes a decoded image obtained by decoding the received image encoding stream. The image receiving device includes a data receiving unit, a parameter changing unit, a decoding unit, and an image recognition unit. The data receiving unit receives an image encoding stream including image encoding data and the parameter. The parameter changing unit changes the parameter received by the data receiving unit, that is, the parameter specified for encoding performed by a sender, to a value suitable for image recognition performed in the subsequent stage. The decoding unit generates the image decoding data by decoding the received image encoding data according to the changed parameter. The image recognition unit performs image recognition on the image decoding data.

摘要： Signal processing including decoding and format conversion is executed on compressed image data at a high speed by simple control.A decoder decodes compressed image data in units of blocks and writes the decoded data in the blocks into a decoded data memory. A progress notification unit generates a progress signal indicating a state of progress that data is being decoded or written into the decoded data memory by the decoder and outputs the signal to a format conversion unit per picture. The format conversion unit reads out the decoded data from the decoded data memory and format-converts the data, and writes the format-converted data into a format-converted data memory. In reading out data from the decoded data memory, the format conversion unit acquires information indicating an address of decoded data readable from the decoded data memory from the progress signal.

摘要： Regarding association between an area where compressed data is stored and an area where auxiliary information required to access the compressed data is stored, it is necessary to manage the association by software for each processing unit, so that the processing becomes complicated. A management unit memory area including a compressed data storage area and an auxiliary information storage area including auxiliary information are defined on a memory space. By calculating an auxiliary information address from an address indicating a location on a memory where a management unit memory space is set, an address of the auxiliary information storage area, and an address of the compressed data, the compressed data and the auxiliary information are associated with each other and the auxiliary information is read.
