  4. Binary-to-text encoding - Wikipedia

    en.wikipedia.org/wiki/Binary-to-text_encoding

    Some encodings (the original version of BinHex and the recommended encoding for CipherSaber) use four bits instead of six, mapping all possible sequences of 4 bits onto the 16 standard hexadecimal digits. Using 4 bits per encoded character leads to a 50% longer output than base64, but simplifies encoding and decoding—expanding each byte in ...

  5. Binary file - Wikipedia

    en.wikipedia.org/wiki/Binary_file

    A hex editor or viewer may be used to view file data as a sequence of hexadecimal (or decimal, binary or ASCII character) values for corresponding bytes of a binary file. [ 2 ] If a binary file is opened in a text editor , each group of eight bits will typically be translated as a single character, and the user will see a (probably ...

  6. Intel HEX - Wikipedia

    en.wikipedia.org/wiki/Intel_HEX

    Intel hexadecimal object file format, Intel hex format or Intellec Hex is a file format that conveys binary information in ASCII text form, [10] making it possible to store on non-binary media such as paper tape, punch cards, etc., to display on text terminals or be printed on line-oriented printers. [11]

  7. LEB128 - Wikipedia

    en.wikipedia.org/wiki/LEB128

    Break the number up into groups of 7 bits. Output one encoded byte for each 7 bit group, from least significant to most significant group. Each byte will have the group in its 7 least significant bits. Set the most significant bit on each byte except the last byte. The number zero is usually encoded as a single byte 0x00.

  8. Variable-length quantity - Wikipedia

    en.wikipedia.org/wiki/Variable-length_quantity

    In this scheme of representation, n bits encode a range from −2 n to 2 n − 1, and all negative numbers start with a 1 in the most significant bit. In Signed LEB128, the input is sign-extended so that its length is a multiple of 7 bits. From there the encoding proceeds as usual. [14] In LEB128, the stream is arranged least significant first ...

  9. SREC (file format) - Wikipedia

    en.wikipedia.org/wiki/SREC_(file_format)

    Byte count - two hex digits ("00" to "FF"), indicating the number of bytes (hex digit pairs) that follow in the rest of the record (address + data + checksum). This field has a minimum value of 3 (2 for 16-bit address field plus 1 checksum byte), and a maximum value of 255 (0xFF). "00" / "01" / "02" are illegal values.
