The present invention relates to a method for making a substantially cylindrical tool from a substantially planar substrate, wherein the tooling has at least one patterned surface. The resulting tooling includes a patterned surface with a sufficiently strong weld that is capable of producing an article having a pattern surface that has a relatively narrow and preferably cosmetically pleasing seam line. Such articles include retroreflective sheeting, structured abrasive articles, adhesive articles suitable for use in personal care products, and the like.

A method and apparatus provides bit manipulation of data in vector registers of a vector register computer system. Matrix multiplication is accomplished at a bit level of data stored as two matrices in a vector computer system to produce a matrix result. The matrices may be at least as large as 64 bits by 64 bits and multiplied by another 64 by 64 matrix by means of a vector matrix multiplication functional unit operating on the matrices within a vector processor. The resulting data is also stored at a 64 bit by 64 bit matrix residing in a resultant vector register.
