Abstract: A prefetch controller is configured to communicate with a prefetch cache in order to increase system performance. The prefetch controller includes an instruction lookup table (ILT) configured to receive a first tuple including a first instruction ID and a first missed data address. The prefetch controller further includes a tuple history queue (THQ) configured to receive an instruction/stride tuple, the instruction/stride tuple generated by subtracting a last data access address from the first missed data address. The prefetch controller further includes a sequence prediction table (SPT) in communication with the tuple history queue (THQ) and the instruction lookup table. The prefetch controller includes an adder in communication with the instruction lookup table (ILT) and the sequence prediction table (SPT) configured to generate a predicted prefetch address and to provide the predicted prefetch address to a prefetch cache.

Abstract: The invention provides a method for transforming an image from a Low Dynamic Range (LDR) image obtained with a given camera to a High Dynamic Range (HDR) image, the method comprising: obtaining the exposure-pixel response curve (21) for said given camera converting the LDR image to HSB color space arrays (22), said HSB color space arrays including a Hue array, a Saturation array and a Brightness array; and determining a Radiance array (23, 24) by inverse mapping each pixel in said Brightness array using the inverse of the exposure-pixel response curve (f?1).

Abstract: A method, computer program product and system for compressing a multivariate dataset. A dataset is selected that includes a plurality of variates. A first compression method is applied to the values of a first variate of the dataset. A second compression method is applied to the values of a second variate of the dataset, where the second compression method is arranged to compress the second variate values relative to the variation of the corresponding first variate values.
