Practical Notes and Notation

  • Unless noted otherwise, all numbers are encoded in big-endian two's complement format (e.g., a 16 bit representation of the number 1000 is encoded as the two bytes 03e8).
  • Numbers need not be aligned to word boundaries. Trying to read unaligned numbers with a 16 bit or 32 bit memory read may produce unexpected results on some CPUs. (In C and C++, unaligned loads depend on parts of the language semantics that are explicitly undefined, so if in doubt, make use to read each byte individually and reassemble later.)
  • The types "u8", "u16", "u32` and "i8", "i16", "i32" refer to unsigned 8/16/32 bit numbers, and to signed 8/16/32 bit numbers (respectively).
