Abstract: A face recognition system comprising an image sensor (100), the output of which is fed to a detection module (102) and the output of the detection module (102) is fed to a recognition module (104). The detection module (102) can detect and localize an unknown number (if any) of faces. The main part of the procedure entails segmentation, i.e. selecting the regions of possible faces in the image.

Abstract: A processing element (1) forming part of a parallel processing array such as SIMD comprises an arithmetic logic unit (ALU) (3), a multiplexer (MUX) (5), an accumulator (ACCU) (7) and a flag register (FLAG) (9). The ALU is configured to operate on a common instruction received by all processing elements in the processing array. The processing element (1) further comprises a storage element (SE) (11), which supports the processing of local customized (i.e. data dependent) processing in the processing element (1), such as lookup table operations and the storing local coefficient data.

Abstract: A decoder circuit, for example a dual-rail decoder, receives input signals (43) from the end of a communications bus (not shown). The parity is calculated over the data wires (Do, D1, D2, D3) using exclusive OR gates (45, 47, and 49). The calculated data parity signal (51) is compared with a transmitted parity signal (53) (shown as “carry”) in an exclusive OR gate (55). Rather than connecting the control signal (57) from the exclusive OR gate (55) directly to the multiplexers (590, 591, 592, 593), the control signal (57) is instead connected to a gating circuit (71). The gating circuit (71), for example a AND gate, receives the control signal (57) as a first input signal. The gating circuit (71) also receives a second input signal in the form of a gating control signal (73). The gating control signal (73) is delayed by a predetermined amount, for example corresponding to the worst case delay of the signals in the input data signals (43).

The device comprises a splitting screen (23, 24, 61, 71) in front of the display screen (22) for splitting the image in a number of sub-images in a number of viewing zones (A,B,C,D), and in operation for each or for each or for a number of viewing zones a different part of a document is visible in a manner such that when tilting the device the parts of the document are visible in a sequential manner. The device may be tilted around a horizontal or vertical axis depending on the orientation of the splitting screen.

Abstract: The invention relates to a device for parallel data processing, a DSP. The device according to the invention comprises a processor matrix (100) in which processors (103) are arranged in rows (101) and columns (102). Furthermore, the device (100) comprises first and second external data ports (107, 108). The rows (101) arranged in a stepwise manner and the columns are arranged in a stepwise manner. The processors (103) have a first processor data port (104), which is connected with one of the first external data ports (107) by means of first essentially straight connection. The processors (103) further comprise a second processor data port (105), which is connected with one of the second external data ports (108) by means of an essentially straight second connection (110). The first connection (107) and the second connection (108) are oriented substantially orthogonal to each other.

Abstract: An electronic device has a data communication bus (200) mounted on a semiconductor substrate (120). The data communication bus (200) has a first conductor (102), a second conductor (104), a third conductor (106) and a fourth conductor (108). The conductors have been reordered and the distances (I1, I2, I3) between two neighboring conductors have been recalculated on the basis of the correlation between the data-bits conveyed by the conductors of the data communication bus (200), e.g. the number of times that the two transitions on two conductors have a predetermined value out of the total number of transitions on that conductor pair. Consequently, a data communication bus (200) is obtained in which the power consumption resulting from the charging of the cross-coupling capacitance between two neighboring conductors is reduced.

Abstract: The electronic device (10) has a data communication bus (12) consisting of a plurality of substantially parallel conductors (12a, 12b, 12c, 12d). A control circuit (14) controls the values driven onto the conductors (12a, 12b, 12c, 12d). Transition dependent delay elements (16a, 16b, 16c, 16d) are coupled between the control circuit (14) and the respective conductors (12a, 12b, 12c, 12d) to delay certain transitions on the data communication bus 12. In particular, one of the opposite transitions on neighboring conductors e.g. a first conductor (12a) and a second conductor (12b) is delayed, thus reducing the power required to charge the mutual capacitance between the first conductor (12a) and the second conductor (12b). Consequently, a data communication bus (12) with reduced power consumption is obtained.
