A decimal multiplication mechanism for fixed and floating point computation in a computer having a coefficient mechanism without resulting leading zero detection (LZD) and process which assumes that the final product will be M+N digits in length and performs all calculations based on this assumption. Least significant digits that would be truncated are no longer stored, but retained as sticky information which is used to finalize the result product. Once the computation of the product is complete, a final check based on the examination of key bits observed during partial product accumulation is used to determine if the final product is truly M+N digits in length, or M+N−1 digits. If the latter is true, then corrective final product shifting is employed to obtain the proper result. This eliminates the need for dedicated leading zero detection hardware used to determine the number of significant digits in the final product. The corrective final product shifting also incorporates adjustments to the coefficient of the product when the product's exponent is at its extremes and the final product must be brought to be within the precision and range of a given format.

Global motion between frames of a motion-compensated inter-frame encoded video sequence is estimated directly from the motion vectors encoded within the frames. For any particular frame, the motion vectors are first decoded, and a finite number of sets of vectors are selected. An affine or other geometrical transform is then used to generate a motion estimation for each set, and then the least median squared error present in each motion estimation is calculated for each estimation. The motion estimation with the smallest least median squared error is then selected as being representative of the global motion in the image of the frame. A panoramic image generating method and system makes uses of the global motion estimations thus obtained.

Storage circuitry is provided with increased resilience to single event upsets, along with a method of operation of such circuitry. The storage circuitry has a first storage block configured in at least one mode of operation to perform a first storage function, and a second storage block configured in at least one mode of operation to perform a second storage function distinct from said first storage function.
