  • Patent number: 4481575
    Abstract: The cycle time of a data processing system should always be determined in such a manner that data from a source register, after having been propagated through, if necessary, several transfer sections and line drivers, and through a chain of logic circuits for the respective processing steps, can be stored in the result or sink register safely and even with the worst case propagation tolerance of all elements involved. The ideal cycle time therefore, which is dependent on the processing speed of the slowest chain of logic circuits, has to have added time segments for the worst case of unprecise clocking.A reduction of the cycle time by the above mentioned added time segments, and if necessary by the propagation delays in the transfer sections and in the line drivers, is achieved when the chain of logic circuits and thus its delay time is divided into two partial chains with the partial delays and if the sink register is arranged between the two partial chains.

  • Patent number: 4400776
    Abstract: An improved data processor control subsystem in which a cycle counter having a plurality of cascade-connected stages also comprises one or more supplemental or dummy stages, which can be selectively inserted or removed from the chain of cascade-connected stages, to alter the number of sub-cycles in an operating cycle, thereby decreasing the complexity of associated decoding circuitry.

  • Patent number: 4398247
    Abstract: In executing and controlling internal data flow for a particular program, it is often necessary to delay execution of an instruction by the insertion of an appropriate number of wait cycles. Thus, it may be necessary to interrupt instruction execution, for example, to insert a given number of wait cycles for channel access to common storage of the data processing system, for reloading a data or instruction buffer, or for a like situation. In such cases, the control unit has to ignore the particular instruction awaiting execution and execute another forced operation instead.An appropriate code is provided for a NO OPERATION instruction, say all bits zero. When a forced operation is to be executed, this code can be generated with fewer logic means at the output of the instruction register. As a result, there are no control signals active at the output of the decoder. The signals indicating forced operations have to be considered by the decoder only if a control signal is to be generated.

  • Patent number: 4231085
    Abstract: In a micro-controlled data handling system the number of lines and pins required to transfer control signals from the microprogram controls to be integrated circuit modules controlled by such signals is conserved by using two bussing paths for distributing the control signals to the modules. A first path is dedicated exclusively to pre-decoded control signal functions and a second path is shared for transferring both data and control signal functions. Each controlled module contains an additional decoding circuit for combinationally decoding control signal functions received through both paths.
