    • Provided are a method and an apparatus for compression transmission of bus data including a plurality of bytes including upper bits and lower bits. The apparatus includes a comparator and an aligner. The comparator compares upper bits of a previous byte with upper bits of a current byte among the plurality of bytes. If the upper bits of the previous byte are identical to the upper bits of the current byte, the aligner compresses the bus data in a combination of a full-byte and a half-byte, by allowing the previous byte to be constituted with the full-byte having bits corresponding to the number of bits of the previous byte and allowing the current byte to be constituted with the half-byte excluding the upper bits of the current byte. Then, the aligner arrays the compressed bus data in a preset bus bandwidth to transmit to a slave device.
    • 提供了一种用于压缩传输包括高位和低位的多个字节的总线数据的方法和装置。 该装置包括比较器和对准器。 比较器将先前字节的高位与多个字节中的当前字节的高位进行比较。 如果前一个字节的高位与当前字节的高位相同,则对齐器以全字节和半字节的组合来压缩总线数据,通过允许前一个字节由完整字节组成 字节具有与先前字节的比特数相对应的比特,并允许当前字节由不包括当前字节的高位的半字节构成。 然后,对准器将预设总线带宽中的压缩总线数据排列成从属设备。
