Unlike processor architectures with variable length or bit instructions, such as the Cray-1 and Hitachi SuperH, both the ARM and Thumb instruction sets exist independently of each other. Retrieved 19 January Timothy Baldwin 1, 1 8 The Acorn Business Computer ABC plan required that a number of second processors be made to arfhitecture with the BBC Micro platform, but processors such as the Motorola and National Semiconductor were considered unsuitable, and the was not powerful enough for a graphics-based user interface.

This results in the typical ARM program being denser than expected with fewer memory accesses; thus the pipeline is used more efficiently.

Typical applications include DRM functionality for controlling the use of media on ARM-based devices, [94] and preventing any unapproved use of the device.
