    Abstract: PROBLEM TO BE SOLVED: To provide a processor and a method for processing matrix data. SOLUTION: The processor includes M independent vector register files which are adapted to collectively store a matrix of L data elements. Each data element has B binary bits. The matrix has N rows and M columns, and L=N*M. Each column has K subcolumns. N>2, M>2, K>1 and B>1. Each row and each subcolumn is addressable. The processor does not duplicatively store the L data elements. The matrix includes a set of arrays such that each array is a row or subcolumn of the matrix. The processor may execute an instruction that performs an operation on a first array of the set of arrays so that the operation is performed with selectivity with respect to the data elements of the first array.

    Abstract: A common requirement for a display adapter for multimedia applications is to be able to support two display "layers" simultaneously accessed from display memory. For each displayed pixel the two display layers are merged with various forms of mixing possible. The obvious way of displaying these two layers is to hold each layer in separate VRAMs and use the VRAM serial ports to access the two layers simultaneously. However, with the low resolution displays and small memory sizes required for personal computers it is not possible to keep the two layers in separate VRAMs, and so both data streams must be fetched from a single VRAM, or bank of VRAMs. With conventional VRAMs this cannot be efficiently achieved. By a novel enhancement to a conventional "Split Shift Register" VRAM, the disclosed invention allows both layers to be accessed simply and efficiently from the same memory device(s). The disclosed invention finds application in the field of semiconductor memory devices, in particular VRAMs and other similar memory devices. The disclosed use of memory devices according to the invention finds application in the field of, but not limited to, display memory subsystems.

    Abstract: Apparatus is provided for adjusting the color of the sprite in display systems, so that the sprite is always distinctively visible irrespective of the underlying displayed data. A palette DAC 322 of a display system is provided with sprite control logic, which determines the color of a sprite to be overlaid on an image displayed on a video display unit 236 of a display system by inverting only the most significant bit (MSB) of each of the red, green and blue pixel data components of the underlying image. In a preferred embodiment, the sprite control logic circuit comprises first, second and third multiplexors (MUXes) 420, 422, 424 each having a first input connected to receive the MSB of the red, green and blue pixel data components of the underlying image, respectively, and a second input connected to receive the output of first, second and third XOR gates, respectively. Each of the first, second and third XOR gates similarly have a first input connected to receive the MSB of the red, green and blue pixel data components of the underlying image, respectively, and a second input connected to receive sprite data from a sprite RAM 324, which sprite data represents a sprite character to be overlaid on the displayed image.
