Architecture Revisions

Architecture revisions augment the fundamental capabilities of the Nios II
architecture, and affect all Nios II cores. A change in the architecture mandates a
revision to all Nios II cores to accommodate the new architectural enhancement. For
example, when Altera adds a new instruction to the instruction set, Altera
consequently must update all Nios II cores to recognize the new instruction.
