Does ARM feel they will avoid infringement on all 32 bit processors? Are they intentionally moving customers to 32 bit architecture to avoid future infringement?

 LONDON — Toshiba Corp. has licensed the Cortex-M3 microcontroller from ARM Holdings plc (Cambridge, England) for use in automotive applications, according to ARM.

Automotive standard infrastructures such as AutoSAR (Automotive Open System Architecture) and JasPar (Japan Automotive Software Platform Architecture) are helping to move the automobile towards 32-bit microcontroller architectures, ARM said.

from 584 "instruction groups" contention

The dispute is whether an operand that is present in the instruction group must be right justified and whether the instruction group may encompass a single 32-bit traditional conventional instruction.
