ABSTRACT:
A routable operand and selectable operation processor multimedia extension unit is employed to stretch pixel bit images in a video system using an efficient, parallel technique. For a series of pixels in a row, a series of interpolation values are established, based on multiples of a reciprocal of a stretch factor. For each interpolation value, the integral portion is used to establish the appropriate two source pixels, and the fractional portion then provides weighting of those pixel values. The various source pixels and interpolation values are routed using the operand routing and operated upon using the vector selectable operations, yielding two destination pixels calculated in parallel.
