摘要： The method of coding data within a data processing unit includes a representation as twos-complement and a coded representation of the data. The coded representation is a semi-negated representation. A data processing unit includes a memory device connected bidirectionally to a data bus, itself connected to a processing architecture which includes at least one arithmetic-logic unit. Advantageously, the data processing unit includes at least one data coding/decoding block connected between the processing architecture and the data bus.

摘要： Digital signals are transmitted on a bus at given instants selectively in a non-encoded format and an encoded format. The decision whether to transmit the signals in non-encoded format or in encoded format is taken in part, based on a comparison of the signal to be transmitted on the bus for an instant of the aforesaid given instants with the signal transmitter on the bus for the preceding instant, so as to minimize switching activity on the bus.

摘要： To execute the cell-search procedure in a cellular communication system (such as a system based upon the 3GPP TDD standard), there are available identification codes for the second step (slot synchronization) and for the third step (identification of the scrambling codes). The identification codes are identified by a process of correlation with the received signal and are used for obtaining from a correspondence table the parameters for the execution of the second step (CD) or of the third step (SCR). The correspondence table is stored in a reduced form by the identification, according to rules of symmetry and redundancy, of subtables designed to generate the entire table by appropriate combination operations. The search procedure in the correspondence table thus reduced is conveniently modified by the introduction of the combination operations. A preferential application is in mobile communication systems based upon standards such as UMTS, CDMA2000, IS95 or WBCDMA.

摘要： Described herein is a method for parallel generating Walsh-Hadamard (WH) channelization codes and Orthogonal Variable Spreading Factor (OVSF) channelization codes, which are channelization codes formed by a plurality of strings of antipodal digits, each having a given length L and being identifiable by respective indices I formed by strings of binary digits, each having a given length N equal to the logarithm in base two of the length L of the channelization codes, the antipodal digits of the channelization codes assuming the values +1 and −1 and the binary digits of said indices I assuming the values 0 and 1. The method according to the invention enables determination of the antipodal digits of the channelization codes according to the binary digits of the corresponding indices I, implementing specific EXOR logic operations, by means of which there are first generated intermediate binary digits, which are then encoded with the antipodal digits of the channelization codes using an encoding criterion according to which the intermediate binary digits 0 and 1 can be encoded, respectively, with the antipodal digits −1 and +1 or else with the antipodal digits +1 and −1 according to the type of binary encoding chosen a priori for the antipodal digits themselves.

摘要： A processor architecture includes a number of processing elements for treating input signals. The architecture is organized according to a matrix including rows and columns, the columns of which each include at least one microprocessor block having a computational part and a set of associated processing elements that are able to receive the same input signals. The number of associated processing elements is selectively variable in the direction of the column so as to exploit the parallelism of said signals. The architecture can be scaled in various dimensions in an optimal configuration for the algorithm to be executed.

摘要： A method for transmitting on an optical connection an input data sequence having first and second logic states, includes encoding the input data sequence prior to transmission on the optical connection, where the encoding minimizes the first logic states in the encoded data sequence. The encoding includes: arranging the input data sequence in parallel on a number of bus lines; counting the first logic states in the input data sequence; comparing the counting result with a value equal to half of the lines; and logically inverting the input data sequence on the lines if the counting result is greater than half of the lines of the input data sequence. The method further includes: ordering values of the input data sequence; identifying the first value having the first logic state; and applying the encoding operation just to the ordered values subsequent to the first value having the first logic state.

摘要： An optimized method of computing the value of the degree of membership of a fuzzy variable defined within a universe of discourse that is discreted into a finite number of points by way of a membership function thereof, wherein the membership function is quantified into a finite number of levels corresponding to a finite number of degrees of truth, and is stored as a characteristic value of each subset of fuzzy variable values being all mirrored in one value of said degree of membership corresponding to one of said levels. The computing method includes generating a binary sequence; generating an address signal from the bits in the binary sequence; reading the contents of the memory storing the membership functions at each address signal to obtain a characteristic value; and comparing the characteristic value with the value of a fuzzy input variable. These steps are repeated until a characteristic value is found that is equal to or greater than the value of the fuzzy input variable, the degree of membership sought being correlated with the address value of the characteristic value.

摘要： A process for transmitting data on a bus, minimizing the switching activity, involves converting the data between a first format and a second format used for transmission of the data. The conversion between said first format and said second format entails the swapping of position of respective bits within a cluster comprising a given number of bits, the swap operation being implementable according to different variants, the maximum number of said variants being equal to the factorial of the aforesaid given number. Each of said variants is identified by a respective pattern. Among the aforesaid patterns, an optimal pattern is selected which minimizes the switching activity at the moment of transmission of data on the bus. The data are then transmitted on the bus using the second format generated using said optimal pattern.
