all the claims in the application. An amendment after final
rejection was filed on April 5, 1995 and was entered by the
examiner.
The disclosed invention pertains to a method and
apparatus for summing plural sections of a single data word.
More specifically, the invention repetitively performs steps
of masking, rotating and summing on larger and larger sections
of the single data word.
Representative claim 1 is reproduced as follows:
1. A method for forming a sum of data in 2 equalN
sections of a single data word comprising the steps of for
each M from 1 to N:
forming an Mth mask having bits of a first digital state
filling M odd alternate sections and bits of a second digital
state filling M even alternate sections, said second digital
state being opposite to said first digital state;
masking a prior sum data word by a first mask thereby
forming a prior sum masked data word, the prior sum data word
for M=1 being the single data word;
rotating the prior sum data word by M sections;
masking the rotated prior sum data word by the Mth mask
thereby forming a rotated prior sum masked data word;
summing the prior sum masked data word and the rotated
prior sum masked data word thereby forming a sum data word, a
