Appeal No. 97-1182
Application No. 08/150,371
The invention is directed to a method and apparatus for
multiplying matrix data.
Representative independent claim 1, the independent
method claim, is reproduced as follows:
1. A method of multiplying matrix data comprising
the steps of:
(a) inputting an input vector data signal to a
matrix multiplying circuit,
(b) multiplying said input vector data signal by a
first constant matrix with said matrix multiplying
circuit,
and
(c) outputting from said matrix multiplying circuit
the result of the multiplying step (b) as an output
vector signal,
wherein said multiplying by a constant matrix step
(b) includes:
(b) (1) resolving with said matrix multiplying
circuit said first constant matrix into a first group of
constant matrices;
(b) (2) further resolving with said matrix
multiplying circuit one matrix of said first group of
constant matrices into at least three finally-resolved
constant matrices, each finally-resolved constant matrix
being composed of elements selected from the following group
0, +1, and - 1; and
(b) (3) multiplying said input vector signal with
said one matrix, said one matrix being resolved to each
