Abstract
- An architecture of a matrix-vector multiplier (MVM) is devised, which is dedicated to MPEG-4 natural/synthetic video decoding. The MVM can perform the matrix-vector multiplication both in the inverse discrete cosine transform (IDCT) and in the geometrical transformation of three-dimensional computer graphics (3-D CG); or, specifically, it can achieve the multiplication of a 4×4 matrix by a four-tuple vector necessary in the one-dimensional IDCT for eight pixels and in the geometrical transformation for a point in a 3-D space. This paper describes a new architecture of this MVM and also shows the implementation result of a functional module composed of four MVMs with the use of 440-k transistors, which can operate at 20 MHz or less [ABSTRACT FROM PUBLISHER]
