### Processor Independence

In deriving the Ultimotion data stream, care was taken to balance the requirements of software-only and hardware-assisted decompression. The resulting data stream:

Uses byte-oriented data organization and simple integer arithmetic (that is, no multiplication or division) so that non-computationally intensive decompression algorithms can be used.

Organizes the data for efficient processing of unwanted data when being scaled during playback.

Data structures are organized for hardware-assisted techniques wherever feasible but do not utilize any particular processor instruction capability .
