Description

one

The invention relates to computing, in particular, to information exchange devices, and can be used in the construction of computing systems.

An informational device is known comprising a priority block, a block of channel register nodes, a buffer memory block, a free zone search block, a timing block, a synchronization block, a control block, parallel and serial channels connecting blocks.

A disadvantage of the known device is the complexity of the structure, which leads to high equipment costs.

It is also known that the device for information exchange containing the first and second registers, the steering unit, the request group, the information group and the control input group, the information output group is closest to the invention of the technical entity and the achieved result. The first output group of the control unit is connected to the first and the second control inputs of the first and second registers, the code inputs of the first register — with a group of device request inputs, the code inputs of the second register, and the first group of inputs Lok control - with a group of steering input device.

The drawback of the device is that it contains functional blocks of heterogeneous structure. This complicates the device and makes it difficult to implement the device based on modern technology.

The purpose of the invention is to simplify the device and increase the regularity of its structure.

This is achieved by the fact that the device contains a multifunction memory block and a tag modifier, the first, second, third, fourth and fifth groups of inputs, the first and second groups of outputs of the multifunction memory block are connected respectively to the outputs of the attribute modifier, the first and second registers, with the group of information inputs of the device, with the second group of outputs of the control unit, with the second group of inputs of the control unit, with the group of information outputs of the device, the third group of outputs of the control unit Chen to the control inputs of feature modifier and enabling input unit multifunctional memory, a fourth input group and which group of information outputs connected respectively with the device code, and outputs attribute modifier inputs.

The block diagram of the device shown in the drawing.

The information exchange device contains a control block 1, a block 2 multifunctional memory, registers 3, 4, a characteristic modifier 5, a group of 6 interrogators, a group of 7 information, a gruno 8 control inputs, a gruntse 9 information outputs, the first control inputs 10, And, respectively, of the first and second registers, second control inputs 12, 13, respectively, of the first and second registers, control inputs 14-17 of the attribute modifier, code inputs 18, 19, respectively, of the second register and attribute modifier, code outputs 20 of the modifier recognized ka, enabling input 21, 22-24 Group 25 inputs and outputs a group of multifunctional memory block group 26, the control unit 27 outputs.

The device has two modes of operation: the mode of forming the address of the served subscriber and the mode of servicing.

In the mode of forming the address of the served subscriber, the device operates as follows.

In the first clock cycle from control unit 1, the control input 10 of register 3 is given a signal allowing reception of word requests into the register received by the inputs of group 6. In the second cycle, the control unit sends a group of 24 inputs of block 2 to the control input 12 of register 3 Signals are received allowing the output of the register contents to a group of 23 inputs of block 2 and the tuning block 2 to read the contents of those numerical rulers with direct conversion, which correspond to a significant discharge of the contents of register 3. As a result, the second clock reads Blowing from the corresponding numeric rulers with direct access and at the outputs of group 9 appears a binary code representing the address of that subscriber, whose priority is higher.

The formed address of the subscriber selected for service enters the outputs of group 9 to all subscribers and causes the connection of the corresponding subscriber for services to the inputs of group 7 or to the outputs of group 9.

The operation of the device in the mode of forming the address of the served subscriber is completed, and the device switches to the service mode.

The operation of the device in the service mode is as follows.

In the first cycle, according to the inputs of group 8 from the subscriber selected for servicing, control unit 1 receives a type of service indication: receiving an iB device with the corresponding logical processing of information from the given subscriber with its temporary storage, or issuing the required information from the device with the required logical processing. In the second cycle, the number of the served subscriber is supplied to the inputs of group 8, and the control unit sends a signal to the control input 13 of the register 4, allowing reception to the register

4 numbers served by the subscriber. At the end of the second cycle, the number 4 of the subscriber is recorded in register 4.

The operation of the device in the third cycle is determined by the type of service.

When information is received, in the third, the control block 1 also generates a signal at the control input 13 of register 4, allowing the output of the contents

of this register, the inputs of group 22 of block 2, and the inputs of group 24 are given signals that set up block 2 to compare the number of the served subscriber present at the inputs of group 22 with signs of numerical rulers with associative treatment.

By a sign equal to the number of the served subscriber, it is possible to refer only to those numerical lines in which the modification constants used in

records information.

If in the third cycle, the number of the serviced subscriber did not occur with a sign of a numeric line, which indicates the absence of information received from the serviced subscriber in the device, then in the fourth cycle, the signal from the control unit 1 to the control input 14 the low order of the attribute modifier 5 is written to one, and the device

proceeds to p the tact work. The coincidence of signs can be judged by the presence of signals at the outputs of the group 25 of block 2.

If a match occurs, then in the fourth cycle, the control unit sends to the inputs

group 24 of block 2 signals that set it to read from the corresponding numerical line Constant for modifying the number of the subscriber to be used when writing information.

The control unit 1 in the same clock cycle supplies the control signals to the control input 15 of the attribute modifier 5. As a result, the modification constant comes from the outputs of group 9 of block 2 to the attribute modifier. In general,

the contents of register 4 and the attribute modifier is the modified number of the subscriber to be served, which is required to record the next information package of the subscriber.

In the fifth cycle, the control unit sends signals to the control inputs 13 and 17 of register 4 and modifier 5 of the feature, to arrange for issuing a modified number of the subscriber to the inputs of group 22

and on the code outputs 20 of the attribute modifier.

In addition, in the fifth cycle, the inputs of the group 24 of the block 2 receive signals from the control block, which set up the block 2 for comparison

Modified number of the subscriber with signs of numeric lines with associative treatment.

If the match is fixed, the subscriber service is delayed, since

The modification constants used for recording and reading information from the same subscriber coincided. Such a coincidence is possible if the number of information messages of this subscriber, stored in block 2, is equal to the recalculation module of the modifier 5 of the feature. Reception of information from such a subscriber is possible only after the output of several (or at least one) information packages of the subscriber from block 2.

If there is no match, the device proceeds to the next cycle.

In the cycle from the control unit, the control inputs 13 and 17 of register 4 and modifier 5 of the feature and the inputs of group 24 of block 2 Receive signals that set up register 4 and the attribute modifier to issue the modified number of the subscriber to the inputs of group 22 of block 2 and outputs 20 feature modifier n tuning unit 2 to record with the required logical processing of information received from the subscriber through the inputs of group 7 and the modified number of the subscriber.

The subsequent clock operations are similar to those of a simple clock cycle until the time allotted for the device to operate in the service mode ends, or if the subscriber service ends before the time allotted for this, which is recorded by the occurrence of the corresponding signals at the inputs of group 8, or if consumed the capacity of unit 2, as reported by the signals at the outputs of group 25 of unit 2.

At the end of the recording of information, there are two final measures.

In the first of the final clock cycles, the control unit 1 sends a signal to the input 14 of the attribute modifier 5, increasing the value of the modification constant by a unit of the least significant bit. In the second cycle, the signals from the control unit to the control inputs 13 and 16 of the register 4 and the modifier 5 of the characteristic set the register 4 to issue the subscriber service number stored in this register to the inputs of the group 22 of the block 2, and the attribute modifier to issue the stored in the constant of modification to the inputs of group 7 of the device. In the same cycle, the signals from control unit 1 to the inputs of group 24 of unit 2 configure block 2 to record the modification together with the number of the subscriber in the free numerical line with the smallest sequence number. As a result, in block 2, the modification constant of the next information packet is recorded in accordance with the subscriber number and its next modification constant.

If in the service mode information was read out, then in the second cycle the control unit is additionally sent a signal to the enable input 21 of unit 2,

providing a record in the table corresponding to the next modification constant used in reading, together with the minimally modified subscriber number.

If in the service mode the device provides information, the device operates in the third and fourth cycles in the same way as in the third and fourth takha when the information is written with the same information that in the third cycle the control unit additionally sends a signal to the enabling input 21 block 2. As a result, in the fourth cycle, the constant is sampled by people

an equal to the minimally modified service number of my subscriber, and in register 4 and the attribute modifier, the modified number of the served subscriber is formed, allowing

appeal to the next read from the block 2 informational parcel of the subscriber.

The operation of the device in the fifth cycle proceeds similarly to its operation in the fifth cycle with

-Price of information with the difference that in case of a match of the modified number of the subscriber being served, with the indication of access to the numeric rulers, the device proceeds to the most accurate operation tact. When there is no match, the device moves to the second .viy of the final clock cycles.

In the sixth cycle, the control spgnals coming from block 1 to the inputs of the group 24 of block 2 provide the setting of block 2 to

output with the required log processing of the content of those numerical lines in which a coincidence was recorded in the previous tact of work. The output is made from the numerical bar with the smallest sequence number.

In subsequent cycles, the device performs operations similar to those of the sixth cycle until the time allotted for operation of the device in the service mode or until the full output of the information message with the given access sign is expired, which is recorded by the corresponding signals at the outputs of group 25 Block 2, or at the request of the subscriber to complete the service, the corresponding signals are received at the inputs of group 8 of the device.

If the output of information has ended due to the complete output of an informational bundle with the given access characteristic, then the control unit sends a signal to the control input 14 of the attribute modifier, thus increasing the value of the modification constant by a unit of the least significant bit, after

which the device proceeds to the fifth cycle of operation.

In the event that the issuance of the information ended on the two remaining ones from the considered priority numbers, the device starts to perform operations on the second final

7

tact considered in the description of the device when receiving information.

After the second closing cycle is completed, the operation of the device in the service mode is terminated.

The device can be used both as a separate unit of computing systems, and as an operational unit of communication channels, hubs and buffer processor islands.

The use of a multifunctional memory unit has greatly simplified the structure of the device, which is reflected in the increase of its regularity.

Improving the regularity of the structure of the device improves its manufacturability in the production of modern technology BIS.
