Abstract
Aspects of the present disclosure relate to an apparatus comprising register circuitry implementing a plurality of registers and processing circuitry to perform data processing operations on data stored in said registers. The apparatus comprises store buffer circuitry to, responsive to a store instruction in respect of given data, temporarily store said given data prior to providing said given data to a memory. Responsive to receiving at the processing circuitry a request to perform a state-saving-triggering operation, the register circuitry is configured to capture in shadow registers of said register circuitry a state of a subset of registers of the plurality of registers, provide the captured state from the shadow registers to the memory.
