CENTRAL CALCULATOR FOR CONTROL COMPUTER SYSTEMS

This invention relates to the field of computing.

There are known central computers for arrays of computing systems containing an arithmetic unit, a calculator control unit, blocks of these numbers and instructions, and buffer digital circuit diagrams of outputs and outputs for communication with input / output devices.

A disadvantage of the known calculators is that the buffer circuits of the digital inputs and outputs are not universal, but are designed to communicate with specific input or output devices. If you need to have a wide range of I / O facilities to the central computer, you must connect an additional I / O control unit located outside the computer, which leads to an increase in equipment.

The goal of the inventor is to introduce the versatility of the central computationally relative 10 to the tiu of external devices, including other computers, digital and analogue channels, external storage devices; the convenience of completing control systems and data processing systems based on central 11th calculator, saving electronic equipment.

To do this, an input / output control unit is introduced into the proposed central computer, in which the decoder of the external device and the decoder of the zones of the connected device groups are connected to the register of the operation code and the address of the control unit by non-arithmetic operations and the current address counter of the memory connected to the address register of the unit ti, the output register of the memory unit through the gates and the information exchange register of the I / O control unit are connected to the terminals of the input registers of the external device control units in, which pin output registers through the mixer, the register exchange unit and valves upravleii input-output connected to the input register pas m whith block.

The drawing shows a simplified block scheme of the proposed calculator with a controllable I / O block.

Block 1 of the arithmetic operations, determining the unip the sequence of operation of the remaining blocks of the central subdivision unit, connecting with the arithmetical device 2. They operate on the numbers, 1, and 3 in memory block 3. To control the operation of the computational device, use the control panel 4 of the control unit 5, which is connected to the power supply unit and the unit of electronic operations. With register 6 codes and addresses

The de-encryptor irizi sa saigia his device via a valve 10, controlled by an immobilizer “output from a block of non-arithmetic ones”, and keys to circuits 11–13 and a second input device, and through a power 14, with a pulse “input to circuits 15-17 The drivers for external input devices. The zone decoder and address amplifiers are connected to the decoder of 18-23 auto-ohm blocks of uiravlepi external devices. In the regional mode, between the central computer and the output device from the output register 24 of the memory block through the network 25, supported by the immobilized output, information is sent from the exchange register 26 of the I / O control unit 27, connected to the input registers 28–30 of the highest output devices. The output registers 31–33 of the input device connectors to the socket of the mixer 34 of the I / O control unit, which is connected to the exchange register via a gate 35 controlled by an input pulse and connected to the input register of 36 memory currents. The shapers 37--39 answers of the highest output devices and shapers 40-42 answers of the third input devices mounted to the assembly of the node.connect to the mixers 43 and 44, connected with the mixer 45 of the response of the equation block by the input-output in the case of fast response 1, their upper devices, or to a register 46 interrupt block 47 and interrupt programs. The interrupt unit and the OBI-5Y mixer are connected to an arithmetic operation unit. When communicating with accumulators and non-working devices, they synchronize, and pulses from the 48-50 synchronization circuits go to the counter 51 of the current address connected to the register 52 of the address block for us. The current address counter is connected to the input register of the block of data, from which the initial address of the memory cell is received, and with the block of arithmetic operations, which gives the reset emulsion and the end of the exchange of information between the central computer and the packed packet or printer. The block of non-arithmetic operations determines the sequence of operation of the remaining blocks of the central calculator in accordance with the commands issued by the memory block. The arithmetic unit operates the iad with numbers, received by them, from the memory block, and transmits the results of the arithmetic operations back to the WELCH memory unit. For coitrol like work calculator and setting the mode. My work is a coitrol unit and remote control.

Legacy devices. The inclusion in the block of 1 and the input-output of the descrambler of the priziak of your devices allows you to connect any type of external device to the computer's calculator, and the pulses that go to the cat () are fed through gates, which are received by the input and output circuits, which are used by the diagrams of the input and output circuits, and the diagrams are supplied to the diagrams by the diagrams of the input diagrams and the num- ber lines that are supplied by the multiplicates and input circuits. and reduce the amount of electronic equipment of decoder devices.

The presence in the control unit of the input-output of the decoder of the zones of the lower devices provides for the territorial separation of the BHCHJ of the devices but into groups, the number of connections between the central computational device and the external devices is kept. After issuing the address and pulse, an exchange of information between the external device and the electronic calculator is performed, but if the external device is an input to the calculator, then the information from its output register through the Hopa intermediate mixer of the input-output control unit, the register obemiya and gates, immovlyaemymi imiulsom "input enters the input

register block pa.m ty. If the pinpoint ycTpoii is output, then the information from the output register of the memory unit through the gates controlled by the pulse "output, enters the register of control

input-output, and from there to the input register to the next device. At the end of the exchange of information between the external device and the calculator of the response (the response impulse output unit generates a device operation termination signal. In the case of high-speed external devices, response impulses are supplied to the input and output control unit's response mixers, which are respectively impulses. "Output, and from them through a common mixer to the block of non-arithmetic operations. In the case of slower devices, response pulses are fed to the interrupt register of the block and interrupt and mm, distributing the mapping time between slow externally connected devices. Switching the response pulses to the ssptetel or block of interrupted programs can be easily accomplished when installing a control system.

With the information between the zeitral, iy .m calculator and external accumulators (magnetic pulses, drums, etc.) and printing, they synchronize them and their pulses into the current output counter of the memory memory register, the initial address of the memory cell block. ti. The current address counter on arrival of a clock pulse parasitizes the current address and transmits it to the memory address register. In this way, information is exchanged between the central computer and the external device with the frequency of the following clock pulses. The last clock pulse is the end-of-exchange pulse, which resets the current-time counter through the block of non-arithmetic operations.

Such a construction of the I / O control block allows the central computer to communicate with external storage and printing devices and the computer with analog and digital sensors of industrial and technological processes, which increases the versatility of the processor and facilitates the layout of the control complexes, and It also allows reducing the amount of equipment required for communication of the central processor with external devices by placing in the unit only those circuits The latter are common to all devices.
