    Abstract: A state transition method and apparatus based on ROHC, and a computer storage medium are disclosed. The method comprises: when a state machine of a compressor is in an IR state, transiting a state of the state machine to an FO state when a decompressor can only successfully parse a static field of a service stream packet header; and transiting a state of the state machine to an SO state when the decompressor can successfully parse the static field and a dynamic field; when the state machine is in the FO state, transiting a state of the state machine of the compressor to the SO state when the decompressor can successfully parse the dynamic field; and when the state machine is in the SO state, transiting a state of the state machine to the FO state when the decompressor fails to parse the dynamic field within a preset time threshold.

    Abstract: 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.
