Abstract

This is a message sorting device for rearranging the sequential time position of message data bits. If the total length of the message to be assembled is n bits, then the sorting device includes n-1 serially connected delay lines D1... Dn-1. Each delay line is preceded by a switch 10, each of which is connected to a control line 12. A control signal on line 12 gates an incoming data bit either into the associated delay line or to the output line 14. Lines 12 are also coupled to And 16 which is in turn connected to switch 18 at the output of the last line D1.

Serial Message Sorting Device

This is a message sorting device for rearranging the sequential time position of message data bits. If the total length of the message to be assembled is n bits, then the sorting device includes n-1 serially connected delay lines D1... Dn- 1. Each delay line is preceded by a switch 10, each of which is connected to a control line 12. A control signal on line 12 gates an incoming data bit either into the associated delay line or to the output line 14. Lines 12 are also coupled to And 16 which is in turn connected to switch 18 at the output of the last line D1.

In circuit operation, if all control lines 12 contain a 1 bit signal, a data bit is transferred from line D1 to the output line 14 and at any switch 10 a data bit is transferred to the next delay line from the preceding one. If a particular control line 12 contains a 0 bit, the data bit from the delay line preceding the switch connected to such control lead is transferred directly to output lead 14. A data bit from delay line D1 is transferred back via lead 20 to the delay line following the switch 10 connected to the control line 12 having the 0 bit. This sorting device thus assures that the complete message transmitted from a terminal appears on output line 14 in consecutive bit times and in the same order as it was read in by the terminal.
