An independent backup mode transfer method and mechanism for digital control computers

An interrupt is provided to a signal processor having a non-maskable interrupt input, in response to the detection of a request for transfer to backup software. The signal processor provides an transfer signal to a transfer mechanism only after completion of the present machine cycle. Transfer to th...

Zusammenfassung:	An interrupt is provided to a signal processor having a non-maskable interrupt input, in response to the detection of a request for transfer to backup software. The signal processor provides an transfer signal to a transfer mechanism only after completion of the present machine cycle. Transfer to the backup software is initiated by the transfer mechanism only upon reception of the transfer signal.
