ABSTRACT:
An electronic data processor includes a computing unit CPU carrying out a main program on the basis of data stored in a central memory MC and transferred to it from a mass memory MM under the control of an ancillary program or "bootstrap" prerecorded in an external unit UE. The latter comprises a read-only memory RP storing the ancillary program, another read-only memory RM containing a set of microinstructions sequentially read out under the control of an address counter CRM to carry out the word-by-word transfer of the ancillary program to the central memory MC, and various components LCM, LSA, CFD for checking the correct performance of these operations and halting the transfer in the event of a malfunction while emitting an alarm signal.
