摘要： A program control unit for a digital data processing installation is described. The program control delivers macrocommands from a macro-command memory, and micro-commands from a micro-command memory. The micro-commands can be delivered singly or in selected combinations. In addition to the main commands in the macro-command memory which act as macro-commands for directly releasing micro-programs, there are also main commands which follow each other and indirectly cause the delivery of one or more micro-commands. Indirect delivery of micro-commands is caused in any case by a machine address of a memory cell, belonging to the pertinent main command, related to the macrocommand memory for another macro-command. At least one auxiliary command which can be called up by different main commands is contained in a memory cell of this type. Each auxiliary command determines, by means of a micro-command machine address related thereto of the memory cell in the micro-command memory, the delivery of this micro-command or the delivery of this microcommand and the micro-command which follows in the micro-command memory.
