SU1246101A1 - Device for synchronizing the recording of information - Google Patents

Abstract

The invention relates to computing and can be used in logic condition analyzers. The aim of the invention is to increase the functionality by providing multi-channel synchronization. A distinctive feature of the device is the ability to ensure the recording of information in the memory according to a given condition, as well as the state change on the information inputs permitted by the mask register. The goal is achieved by introducing a register of a mask, a group of AND elements, an OR element, a trigger and a delay element, 1 Il. with (L

Description

The invention relates to computing technique and can be used, for example, in logic condition analyzers.

The purpose of the invention is the expansion of functional possibilities due to the formation of a signal accompanying information.

The drawing shows a block diagram of the device.

The device contains a group of 1 information inputs, triggers of 2 groups, 3 comparison blocks, a group of 4 information outputs of the device, an output 5 of the device start signal, the first 6 and a second 7 groups of input start-up conditions of the device, a clock input 8 of the device, a mask register 9, And 10 elements groups, element OR 11, trigger 12, delay element 13, entry mask resolution input 14, element 15.

The device works as follows.

Upon receipt of the mask recording write signal at input 14, the mask code preliminarily set using the sync word switch is written to register 9. With the arrival of a sync signal on clock input 8 or when the information input in the group 1 of the corresponding combination appears on the input of the element OR 1 1 and then, at the output of the trigger 12, a signal is formed that records the signals from group 1 of information inputs into the triggers of group 2.

At the same time, a delay element 13 is triggered by a signal from the inverse output of the trigger 12. After the occurrence of the signal at the output of the delay element 13, the trigger 12 is reset to the initial zero state. Element 13 delays the change of information in the 2.1-2.P triggers for the time it takes, for example, to write it to the memory.

If the sync word coincides with the state of 2.1-2.P triggers, blocks 3.1-3.p. comparisons produce signals arriving at the inputs of the AND 15 element, then at the output 5 of the device; control signal of the state of the inverse outputs of the trigger 2.1-2. P in memory

In this way, the synchronization device 1 × O allows monitoring the state of the input signals by a clock signal or by reading the state on the inputs permitted by the contents of the mask register, to implement multi-channel synchronization of information recording.
