Methods and device for ensuring correct pre-decoding. RU patent 2405188.

FIELD: information technology.

SUBSTANCE: method involves defining a granule which is equal to the smallest length instruction in the instruction set and defining the number of granules making up the longest length instruction in the instruction denoted MAX. The method also involves determining the end of an embedded data segment, when a program is compiled or assembled into the instruction string and inserting a padding of length MAX-1 into the instruction string to the end of the embedded data. Upon pre-decoding of the padded instruction string, a pre-decoder maintains synchronisation with the instructions in the padded instruction string even if embedded data are randomly encoded to resemble an existing instruction in the variable length instruction set.

EFFECT: ensuring reconstruction during repeated synchronisation owing to reduced errors of synchronising the mechanism for pre-decoding the instruction string.

Error handling for early decoding through branch correction / 2367004
Invention relates to processors with pipeline architecture. The method of correcting an incorrectly early decoded instruction comprises stages on which: the early decoding error is detected and a procedure is called for correcting branching with a destination address for the incorrectly early decoded instruction in response to detection of the said error. The early decoded instruction is evaluated as an instruction, which corresponds to incorrectly predicted branching.

Hybrid microprocessor / 2359315
Present invention relates to computer engineering and can be used in signal processing systems. The device contains an instruction buffer, memory control unit, second level cache memory, integral arithmetic-logic unit (ALU), floating point arithmetic unit and a system controller.

Processing of message digest generation commands / 2344467
Command of message digest generation is selected from memory, in response to selection of message digest generation command from memory on the basis of previously specified code of function, operation of message digest generation, which is subject to execution, is determined, at that previously specified code of function defines operation of message digest calculation or operation of function request, if determined operation of message digest generation subject to execution is operation of message digest calculation, in respect to operand, operation of message digest calculation is executed, which contains algorithm of hash coding, if determined operation of message digest generation subject to execution is operation of function request, bits of condition word are stored in block of parameters that correspond to one or several codes of function installed in processor.

Digital signal processors with configurable binary multiplier-accumulation unit and binary arithmetic-logical unit / 2342694
Present invention pertains to digital signal processors with configurable multiplier-accumulation units and arithmetic-logical units. The device has a first multiplier-accumulation unit for receiving and multiplying the first and second operands, storage of the obtained result in the first intermediate register, adding it to the third operand, a second multiplier-accumulation unit, for receiving and multiplying the fourth and fifth operands, storage of the obtained result in the second intermediate register, adding the sixth operand or with the stored second intermediate result, or with the sum of the stored first and second intermediate results. Multiplier-accumulation units react on the processor instructions for dynamic reconfiguration between the first configuration, in which the first and second multiplier-accumulation units operate independently, and the second configuration, in which the first and second multiplier-accumulation units are connected and operate together.

Processing of message authentication control commands providing for data security / 2327204
Invention pertains to the means of providing for computer architecture. Description is given of the method, system and the computer program for computing the data authentication code. The data are stored in the memory of the computing medium. The memory unit required for computing the authentication code is given through commands. During the computing operation the processor defines one of the encoding methods, which is subject to implementation during computation of the authentication code.

Method and device for shuffling data / 2316808
In accordance to shuffling instruction, first operand is received, which contains a set of L data elements, and second operand, which contains a set of L shuffling masks, where each shuffling mask includes a "reset to zero" field and selection field, for each shuffling mask, if the "reset to zero" field of shuffling mask is not set, then data indicated by shuffling mask selection field are moved, from data element of first operand, into associated data element of result, and if "reset to zero" field of shuffling mask is set, then zero is placed in associated data element of result.

Expandable communication control means / 2313188
Expandable communication control means is used for maintaining communication between computing device and remote communication device. In a computer program adapted for using expandable communication control means, information about contacting side is found, and on basis of found contact information it is determined which types of transactions may be used for communication with contacting side at remote communication device. As soon as communication setup function is determined using contacting side information, communication setup request, associated with such a function, is dispatched to communication address. After receipt, expandable communication control means begins conduction of communication with remote communication device.

Configurable computing device / 2291477
Device consists of two computing device units, each of them divided into at least four subunits, which consist of a quantity of unit cells. Named units are spatially located so that the distance between unit cell of first unit and equal unit cell in the second unit is minimal. Computing device configuration can be changed using configurational switches, which are installed between device subunits.

Method for processing with use of one commands stream and multiple data streams / 2279706
System is disclosed with command (ADD8TO16), which decompresses non-adjacent parts of data word with utilization of signed or zero expansion and combines them by means of arithmetic operation "one command stream, multiple data streams", such as adding, performed in response to one and the same command. Command is especially useful for utilization in systems having a data channel, containing a shifting circuit before the arithmetic circuit.
