A program distribution system capable of discarding a distributed program according to the properties of the program is provided. In the program distribution system, a program is distributed from a program transmission apparatus to a program reception terminal over a network. The program transmission apparatus includes a transmission processing section. The program reception terminal includes a reception-side storage section and a discard processing section. The transmission processing section transmits a program and discarding procedure information to the program reception terminal. The discarding procedure information relates to a procedure of discarding the program performed by the program reception terminal. The reception-side storage section stores the program transmitted from the transmission processing section. The discard processing section discards the program stored in the reception-side storage section according to a discarding procedure specified by the discarding procedure information transmitted from the transmission processing section.

A program conversion apparatus that converts a source program to an executable program, the source program including a first descriptor indicating dynamic memory allocation. The program conversion apparatus includes a specifying unit and a generating unit. The specifying unit specifies in the source program a reference descriptor that is last to be executed from reference descriptors indicating references to memory allocated by the first descriptor. The generating unit generates an instruction for freeing the allocated memory at a position in the executable program immediately following an instruction that corresponds to the specified reference descriptor.

A image providing device provides a user with realistic and natural past-experience simulation through stereoscopic photographs. Specifically, feature-point extractors extract feature points from a foreground image and a background image, respectively. A stereoscopic matching module searches for pairs of feature points matching between the foreground image and the background image and obtains using the feature point pairs a transformation matrix for projecting the foreground image onto the background image. The transformation by the transformation matrix obtained by the matching unit is applied to foreground depth data, which is depth data of the foreground image. Lastly, depth based rendering is performed based on the transformed foreground depth data to obtain two or more viewpoint images corresponding to the foreground image.

Java bytecode for having home appliances perform a cooperative operation is developed by a development computer and is sent via a communications satellite from the development computer to a TV tuner&home server provided in a home. After the TV tuner&home server receives the Java bytecode, a bytecode converting unit of the TV tuner&home server determines which home appliance is the target appliance of the Java bytecode and converts the Java bytecode into native code for the microprocessor provided in the target appliance. The native code is downloaded into the target appliance via a home appliance network and the target appliance executes the downloaded native code.

A compiler comprises a loop detecting unit for extracting information of loops, and a high-speed loop applying unit generating a first loop exclusive instruction, placing the instruction immediately before the entry of a loop, generating second loop exclusive instructions, and placing the instruction at each place to branch to the entry of the loop. A processor comprises: a pipeline comprising: an instruction fetching unit, an instruction decoding unit, and an executing unit; a branch target storage unit; a branch target registering unit for, after the instruction decoding unit has decoded a first loop exclusive instruction, registering branch target information of an instruction succeeding to the first loop exclusive instruction in the branch target registering unit; and a branch executing unit for, after the decoding unit has decoded a second loop exclusive instruction, judging whether to execute a loop, if judges to execute, reading the branch target information registered in the branch target storage unit, and controlling the pipeline so that the program executes the loop using the read branch target information.

A image providing device provides a user with realistic and natural past-experience simulation through stereoscopic photographs. Specifically, feature-point extractors 15 and 22 extract feature points from a foreground image and a background image, respectively. A stereoscopic matching module 25 searches for pairs of feature points matching between the foreground image and the background image and obtains using the feature point pairs a transformation matrix for projecting the foreground image onto the background image. The transformation by the transformation matrix obtained by the matching unit is applied to foreground depth data, which is depth data of the foreground image. Lastly, depth based rendering is performed based on the transformed foreground depth data to obtain two or more viewpoint images corresponding to the foreground image.

An electronic publication viewer (1000) includes a display target specifying unit (1100) that specifies a display target page and the position and size of the display target region, a page structure data obtaining unit (1200) that obtains page structure data corresponding to the display target page, a rendering unit (1300) that generates the display image data corresponding to the position and size of the display target region, a display image data caching unit (1400) that caches the display image data, and a display control unit (1500) that causes the display image data obtained from the rendering unit (1300) or the display image data caching unit (1400) in a position of a display unit superimposed on the display target region.
摘要:
A processor detects a function which includes no function call instruction and no update of the return address /calculation register from an assembler program. After the detection, the processor outputs a special return address to the end of the function detected, and executes the assembler program. The processor stores a return address not only on the stack but in the return address/calculation register. When the special return instruction has been fetched, the return address is moved from the return address/calculation register without accessing to the stack.
