Abstract

This merging system provides a continuous flow of records from a sequential storage which can have discontinuities in its output. As shown, two parallel input streams 10 and 12 of, for instance, eight bits each, are being merged.

Providing Continuous Flow of Data From and to Sequential Readout Storage

This merging system provides a continuous flow of records from a sequential storage which can have discontinuities in its output. As shown, two parallel input streams 10 and 12 of, for instance, eight bits each, are being merged.

Five bits of stream 10 are to be followed by three bits of stream 12 to form output stream 14. The three bits of stream 12, designated 2. 0, 2. 1 and 2. 2, are read first and are delayed eleven bit-periods in path 20 by two delay lines 22 and 24. The five bits from stream 10, designated 1. 3... 1. 7, are read and delayed five bit-periods in path 26 by delay line 30.

The outputs of control flip-flops A and F determine which input stream is directed to which path and for how many bit-periods. In control circuit 28, register 32 is set with the number (3) of bits to be most delayed and register 34 is set with its complement 6. Register 34 increments each bit-period and its overflow is used to set flip-flop F. The gates in circuit 28 are enabled by signal S, which occurs every eighth bit-period.
