Abstract

The subject matter of the application essentially relates to a matrix array of processor units, each processor unit having, in addition to an arithmetic logic unit and a result register bank, a further arithmetic logic unit, a multiplier/adder unit, a storage unit of a distributed screen section buffer and a local general purpose memory. The processor is distinguished by a high processing speed in conjunction with a small chip area and enables real-time processing even in the case of computation-intensive image processing methods such as 2D convolution, Gabor transformation, Gaussian or Laplacian pyramids, block matching, DCT or MPEG2.
