Abstract
A processing apparatus has a processor comprising a plurality of deferred-push processor registers and processor-register control circuitry. The processor-register control circuitry comprises a plurality of status registers, each status register corresponding to a different respective deferred-push register. The processor-register control circuitry is configured to: detect a write of a new value to a register of the deferred-push registers; and determine whether the status register for the deferred-push register has a first value, indicative of an unsaved status for the deferred-push register. The processor-control circuitry is configured, when the status register has the first value, to: read a current value from the deferred-push register before the writing of the new value to the deferred-push register completes; write the current value to a memory; and set the status register for the deferred-push register to a second value, indicative of a saved status for the deferred-push register.
