Abstract Digital words of a pipelined incoming information flow are branched into a number of outgoing information flow branches. The term "pipelined" means that the flow is transferred through memory means whose activation inputs are controlled by clock pulses, the memory means arranged successively with reference to the flow direction being coincidently activated to receive successive words of the flow. A digital branching information flow for ordering into which of the outgoing branches the incoming words have to be branched is generated in step with the incoming flow. The basis for each outgoing branch is obtained from the output of a branching register to which the incoming flow is supplied. The branching registers are activated by the clock pulses, but if an outgoing branch contains only a part of the incoming flow, an activation locking device is used in order to block the clock pulses in dependence on the respective branching information. The branching information flow may be transferred to the locking devices through branching information registers whose activation inputs may also be controlled by locking devices. A branching information register is, however, not to be controlled by the locking device connected to its own output.
Information processing apparatus comprising: a source of clock pulses; source means for generating a flow of digital information words and a flow of pluralities of digital braching bits, the flow being synchronized with the clock pulses; a plurality of information word registering means connected to said source means for receiving at least parts of the digital information words therefrom in response to the clock pulses; a plurality of clock pulse synchronized locking means coupled to the plurality of information word registering means, each of said locking means receiving the branching bits and generates an enabling signal for controlling the receipt of said at least parts of the digital information words by an associated information word registering means; a first branching bit registering means connected to said source means for receiving branching bits therefrom, in response to clock pulses, and connected to the associated locking means for emitting thereto the pluralities of digital branching bits for controlling the associated information word registering means to receive the digital information words; and a second branching bit registering means connected to said source means for receiving branching bits therefrom, in response to said enabling signals other than the clock pulse, and connected to the associated locking means for emitting thereto the pluralities of digital branching bits.
