Abstract: To obtain frame synchronization and identify the cell codegroup in a cellular communication system (such as a system based upon the standard 3GPP FDD), there are available the synchronization codes (SSCH) organized in chips or letters transmitted at the beginning of respective slots. Slot synchronization is obtained previously in a first step of the operation of cell search. During a second step, there are acquired, by means of correlation (10) or fast Hadamard transform, the energy values corresponding to the respective individual letters with reference to the possible starting positions of the corresponding frame within the respective slot. Operating in a serial way (24) at the end of acquisition of the aforesaid energy values of the individual letters, or else operating in parallel, the energies of the corresponding words are determined. Of these eneriges only the maximum word-energy value and the information for the corresponding starting position are stored in a memory structure (22). Said maximum value and said starting position identify, respectively, the cell codes and the frame synchronization sought. A preferential application is in mobile communication systems based upon standards such as UMTS, CDMA2000, IS95, or WBCDMA.

Abstract: A method for automatic gain control, e.g. in a receiver for a mobile telecommunication system comprises the operations of:

mixing (13) a received signal (S in ) with an error signal ( P err , P f );
performing an analog-to-digital conversion (14) on the result of said mixing operation, in order to obtain a controlled output signal ( x(t) , S out );
measuring (25) the power ( P meas ) of said controlled output signal (x(t), S out );
subtracting the measured power (P meas ) from a reference power ( P ref ) in order to obtain said error signal ( P err , P f ).

According to the proposed method the operation of measuring the power of the controlled output signal ( x(t) , S out ) comprises:

setting at least a power threshold ( T h ;T h1 , T h2 , T h3 );
measuring (27) a rate of crossings of said power threshold ( T h ; T h1 , T h2 , T h3 ) by said controlled output signal ( x(t) , S out ) in a given observation window;
deriving (29) from said number of crossings the measured power value ( P meas , σ 2=1 ).

The proposed method is particularly suitable for application in receivers of mobile telecommunication systems based on CDMA (Code Division Multiple Access), but also for mobile telecommunication system according to GSM, UMTS, CDMA2000, IS95 o WBCDMA standards and satellite telecommunication systems.

Abstract: Digital video signals, such as the signals generated by an image sensor (1) in a Bayer format, in which the pixels of each line are alternatively coded with two colours, and then converted into an encoded format. In the encoded format, the pixels of the digital video signals are reordered into sets of adjacent pixels, such that the sets group pixels coding the same colour. The encoded signal data is suitable for transmission over a bus (B) in conditions of reduced switching activity.

Abstract: A data cache memory coupled to a processor architecture including a plurality of processor clusters (Cluster0,..., Cluster3) is adapted to operate simultaneously on scalar and vectorial data by providing in the data cache memory data locations for storing therein data for processing by the architecture, and accessing the data locations in the data cache memory either in a scalar mode or in a vectorial mode. This is done preferably by explicitly mapping those locations of the cache memory considered as scalar and those locations of the cache memory considered as vectorial.
