Abstract
A data processing apparatus is provided comprising first processing circuitry, second processing circuitry and shared processing circuitry. The first processing circuitry and second processing circuitry are configured to operate in different first and second power domains respectively and the shared processing circuitry is configured to operate in a shared power domain. The data processing apparatus forms a uni-processing environment for executing a single instruction stream in which either the first processing circuitry and the shared processing circuitry operate together to execute the instruction stream or the second processing circuitry and the shared processing circuitry operate together to execute the single instruction stream. Execution flow transfer circuitry is provided for transferring at least one bit of processing-state restoration information between the two hybrid processing units.
