    摘要: The present application discloses a data transmission method and apparatus. A specific implementation of the method includes: receiving to-be-transmitted data sent from an information sending end, and determining a sending coding type of the to-be-transmitted data; determining a receiving coding type of an information receiving end receiving the to-be-transmitted data; converting the to-be-transmitted data from the sending coding type to the receiving coding type using a preset transcoding model, to obtain transcoded transmission data, the transcoding model representing a corresponding relationship between the sending coding type and the receiving coding type; and sending the transcoded transmission data to the information receiving end. This implementation improves the data transmission efficiency.

    摘要: An encoding device searches input text data for a date-time notation string that represents at least a date or time. The encoding device generates, upon finding the date-time notation string by the search unit, a converted date and time code including an identification code for identifying the date-time notation string and a normalized date and time notation formed by converting the date-time notation string into a specific date-time notation format. The encoding device converts the input text data based on conversion information that associates the converted date-time code generated by the generation unit with the date-time notation string.

    摘要: Base64 encoding and decoding advances are characterized. Some embodiments rely on only a single bit shifting operation; some have no reliance on bit-shifting. Some access data source bytes with multi-byte reads, and use those data source bytes as indexes into an encoding lookup table. Some use a table with four quadrants, each of which contains a copy of the same 64 encoding values. Some use a negative value as both a counter and an index. Some exclude BSWAP instructions even with a little-endian processor. Some partition a data source into N partitions, which are then encoded or decoded concurrently. In some, partition length is based on expected processor performance. Unrolled loops, exemplary assembly language code and coding choices, division using MagicNumber multiplication, terminal null addition, encoding/decoding applications, and other examples are also presented.

    摘要: According to an embodiment of this invention, an information processing apparatus that executes, by a processor, a program including a first program layer with an instruction set to be interpreted and executed by the processor and a second program layer with an instruction set interpreted in advance by a unit other than the processor has the following arrangement. That is, the first program layer holds image data to be processed in a first format. On the other hand, the second program layer holds it in a second format. When transferring image data between the first program layer and the second program layer, the format of the image data is converted between the first format and the second format.
