Description

The proposed device relates to digital signal processing, can be used in devices for image and sound processing, namely processing of bit data at the output of the device, and is intended for use in data processing systems in conjunction with a microprocessor in order to accelerate the processing of bit streams in decoding devices for compressed digital data ...

It is known "a device for gluing / masking, rotating / shifting and Boolean operations for two systems of instructions executed on a vector multiplexer in a double ALU" (US patent 5,781,457), including: "register of the first operand, register of the second operand, byte stretcher for copying byte operand in ALU, result output register ... ".

The main disadvantage of this device (US patent 5,781,457) is that the results of the gluing and shift functions are available only at the third step (at the third sync pulse) with a loss of system speed, the complexity of organizing the operation of the device blocks.

Also known is a device "microprocessor for processing bit streams in compression / decompression systems" (US patent 6.144.321.)

The disadvantages of this device are its significant limitations: the functions of gluing and shifting data of two 32-bit words in a system with a 32-bit data representation are not solved, which limits its large-scale application and makes it capable of solving a narrow range of problems.

The closest in technical essence, the achieved positive effect and adopted by the authors as a prototype device for processing bit streams in compression / restoration systems for audio and video data, (RU 2380738 C1, G06F 7/00 ^(2006.01) , publ. 01/27/2010 Bull. No. 3 ) including "the register of the first operand, the register of the second operand, the result output register, the block for performing the gluing operation, the block for performing the reversal-permutation operation ... etc."

The disadvantages of the prototype are the inability to process large digital data streams in real time, the complexity of the design, and insufficiently high speed of information processing.

The task to be solved by the claimed utility model is to create a device that allows to quickly process large volumes of information flows in real time, increase the speed of information processing and simplify the design of the device.

The technical result is achieved by the fact that a device for processing bit streams in compression / restoration systems of digital information, including a register of the first operand, a register of the second operand, a result output register, a block for performing a gluing operation, a block for performing a byte reversal operation, a block for performing an operation shift, while the registers of the first and second operands are connected to an additionally installed unit for ranking information-accelerator connected to the unit for processing information in which are combined: a unit for performing a gluing operation; a block for performing the byte reversal-swapping operation; a block for performing a shift operation; and which is connected to an additionally inserted information conversion unit, which is further connected to the result output register.

The device is represented by a block diagram in figure 1, where 1 is the register of the first operand; 2 - register of the second operand; 3 - block for ranking information-accelerator; 4 - an information processing unit, including, to simplify the whole structure, a unit for performing a gluing operation, a unit for performing a byte reversal-permutation operation, a unit for performing a shift operation; 5 - block for converting information; 6 - result output register.

The device works as follows. Information flows are received, including in real time, from the register of the first operand 1 and from the register of the second operand 2 to the information ranking unit (accelerator) 3, in which, to speed up the speed of further information processing, it is divided into static, dynamic ones, which will allow further information processing unit 4 individually work with each type of images, then, divided into static and dynamic images, the data streams enter block 4, where they are processed, after which the streams go to block 5, where they are converted, which makes it possible to significantly reduce the volume of the data stream coming further to the output register of the result 6, and thereby avoid overloading the entire system, increasing its reliability.

This device with a simplified design and increased reliability allows to quickly process large volumes of information flows in real time, with an increased information processing speed.
