Abstract: A circuit arrangement is provided for controlling a known logical switching network for shifting data of variable widths, wherein the shift amount by which the data bits applied to the input are to be shifted is switched from the true value to the complement value and vice versa by means of a control signal influenced by control commands, and wherein the partial results thus produced are logically combined to form a further partial result or the final result.

Abstract: A controlled memory access system with a working store and control programme is suited to micro-programmed data processing systems. The main dynamic store consists of an addressable section with input-output controlled by a general machine control programme. A cyclic memory section is loaded by the system user and is not addressable. Data transfer to and from the cyclic memory is under the control of a I/O programme coupled to read and write magnetic disc stores. A general control programme store communicates with the cyclic memory and can generate jump instructions. The system provides flexibility of operation of various sub-routines with different characteristics and programme systems.
