Abstract: The synchronising arrangement is for a processor and memory in an electronic data processing installation. There is a delay from the memory when data is demanded from it by the processor. A section of the arrangement has an output to the operations register of the processor for the provision of a code combination corresponding to a certain micro-instruction lasting for the duration of the memory delay. The operations decoder provides a corresponding output signal which stops the demand cycle counter. The operations register loads the next operation code existing at its input when it receives the next pulse of the system.

Abstract: A control switching network is used in the programming circuit of a digital calculator. The processing unit is connected to a process timing and control unit. This unit is connected to a data store via a set of the intermediate connections. A system is used to keep the store in synchronism with the processing unit. An identification network is used, which produces a signal controlling the action of the store. Store activity monitoring signals are used, and instructions are given to the store in a series of given cycles.
