摘要： A multi-bit accumulator includes 1-bit Wallace trees each configured to perform an add operation on single-bit input data, tristate logic circuits each configured to output a result of the add operation of the 1-bit Wallace trees according to an enable signal provided to the tristate logic circuits, and a shift-adder configured to perform an accumulation operation on the result of the add operation of the 1-bit Wallace trees by a shift operation based on a clock signal.

摘要： A method for assisting with the navigation of a fleet of vehicles including a main vehicle and a secondary vehicle that is mobile in relation to the main vehicle, the method including receiving relative movement data, acquired by one or more sensors, between the main vehicle and the secondary vehicle, estimating a navigation status of the fleet of vehicles by an invariant Kalman filter using the received data as observations, the navigation status including first variables representing a first rigid transformation linking a location mark associated with the main vehicle to a reference point, and second variables representing a second rigid transformation linking a location mark associated with the main vehicle to a location mark associated with the secondary vehicle, the invariant Kalman filter using, as an internal composition law, a law including a term-by term composition of the first rigid transformation and the second rigid transformation.

摘要： Methods of calculating a square of an input number in hardware logic are described. An m-bit number is received and Booth encoding is performed on different groups of three consecutive bits selected from the input to generate an encoded value for each of the groups. For each group, the method comprises forming a truncated string from the input number, generating an updated version of the truncated number and selecting a bit string based on the encoded value, the selected bit string comprising zeros or a left-shifted version of the updated version of the truncated number sign extended to a bit-width of 2m bits. The method further comprises combining the selected bit strings and square and sign bits for each group into an addition array; and summing the bits in the addition array.
