Arrangement for reading out defined data from a digital switching device with mutually asynchronous control signals for sequential switching of the device and transfer of the data |
摘要 |
Arrangement for reading out defined data from a digital switching device with asynchronous control signals for sequential switching of the device and transferring of the data from another switching device. The arrangement includes circuits for applying a signal to the other switching device for sequentially switching the other device and a buffer memory for temporarily storing state variables of the first switching device and circuits for applying a read pulse to the second-mentioned switching device together with circuits for transferring the state variables stored in the buffer memory to the first-mentioned switching device. The arrangement further includes a cross-coupled gate arrangement including at least two cross-coupled gates of which the first one has an input impressible with a clock pulse and the second one has an input impressible with a read pulse, and wherein the first one gate has an output delivering a transfer signal, and circuitry for applying the transfer signal to an input of the buffer memory.
