An external CPU can be used to perform some data processing as the SIMCOP hardware accelerators do. A similar mechanism to the START/DONE pulse interaction with the SIMCOP hardware accelerators is implemented.
The external CPU receives the request to start processing by the CPU_PROC_START_IRQ interrupt merged at the SIMCOP subsystem level. This interrupt is enabled and acknowledged as usual.
When processing has completed, the CPU generates the DONE pulse to the hardware sequencer by writing 1 into the SIMCOP_HWSEQ_CTRL[10] CPU_PROC_DONE register.
