摘要： 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. By thus splitting the chain of logic circuits into two partial chains, the logic partial functions can be executed during that time segment which is composed of the above mentioned added time segments.
摘要翻译：数据处理系统的周期时间应该总是以这样的方式来确定，即来自源寄存器的数据在必要时被传播通过若干传输部分和线路驱动器，并且通过用于相应处理的逻辑电路链步骤，可以安全地存储在结果或接收器寄存器中，甚至在涉及的所有元素的最差情况下传播容差。因此，理想的循环时间取决于最慢链逻辑电路的处理速度，必须为最不稳定的时钟的最坏情况添加时间段。当逻辑电路链和其延迟时间被分成两部分链时，通过上述添加的时间段减少循环时间，并且如果必要，通过传输部分和线路驱动器中的传播延迟来实现具有部分延迟，并且如果宿寄存器布置在两个部分链之间。通过这样将逻辑电路链分成两部分链，逻辑部分功能可以在由上述添加的时间段组成的时间段期间执行。

摘要： 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.If the control signals need be grouped for physical reasons, it is possible to determine which of these signals are a function of forced operations. This will negate the need to otherwise distribute these control signals throughout the decoder, thereby reducing and simplifying the wiring required.

摘要： 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.
