Abstract:
A data processing system is operable in a first state to use a first instruction set having a first instruction set encoding. The data processing system is also operable in a second state to use a second instruction set having a second instruction encoding. Conditional branch instructions provided within the two different instruction sets are arranged to use the same instruction encoding.
