A circuit for enhancing the resolution of a numerical value in existing circuitry using a scalable fixed-point binary format. The scalable fixed-point format positions the bit representing the lowest numerical value (the resolution) with the greatest bit index. The circuit separates the bit representing the lowest numerical value from the remaining portion of a binary encoded number. Legacy processing can be performed on the remaining portion of the binary encoded number. The removed bit is used to select between legacy processing and the output of new processes and / or circuits. The scalable fixed-point binary format can be used to represent modulation and coding schemes (MCS) in a wireless communication standard allowing for new MCS identifiers to be added between existing MCS identifiers using enhanced resolution and while maintaining a monotonic relationship between the identifier and the effective data transfer rate of the MCS.

The invention relates to a communication device with a scalable fixed-point numerical format. A circuit for enhancing the resolution of numerical values in existing circuitry using a scalable fixed-point binary format is provided. The scalable fixed point format locates bits representing a lowest value (resolution) at a maximum bit index. The circuitry separates the bits representing the lowest value from the remainder of the binary coded number. A legacy processing may be performed on the remainder of the binary encoded number. The removed bits are used to select between legacy and new processing and / or an output of a circuit. The scalable fixed-point binary format may be used to represent a modulation and coding scheme (MCS) in a wireless communication standard, allowing new MCS identifiers to be added between existing MCS identifiers using enhanced resolution while maintaining a monotonic relationship between the identifiers and the effective data transfer rate of the MCS.

This invention discloses a high-speed communication method and apparatus. By identifying the performance characteristic parameters of the physical communication interface in real time and combining them with the analysis of the characteristic information of the original communication data, the optimal processing strategy is dynamically generated. By constructing a strategy decision function to perform adaptive compression processing on the data, data redundancy can be eliminated to the greatest extent, generating smaller compressed data blocks. This directly reduces the number of bits that need to be transmitted on the physical link, thereby significantly improving the effective data transmission rate on bandwidth-limited interfaces. During the encryption stage, the encryption working mode is selected according to the characteristics of the compressed data block to ensure the alignment of processing boundaries and avoid the additional overhead and delay caused by data padding and reassembly. Furthermore, the perception and decision-making mechanism does not only operate in the initialization stage but can run throughout the data transmission process. When network congestion, interface switching, or sudden changes in data characteristics are detected, the system can re-evaluate and adjust the strategy in real time.
