ALEXANDRIA, Va., March 14 -- Altera, San Jose, Calif., has been assigned a patent (8,396,914) developed by Martin Langhammer, Alderbury, United Kingdom, for a "matrix decomposition in an integrated circuit device."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "Circuitry speeds up the Cholesky decomposition of a matrix. The circuitry can be provided in a fixed logic device, or can be configured into a programmable integrated circuit device such as a programmable logic device. The circuitry implements the following equation: ##EQU00001## When any l.sub.ij term is calculated this way, the latency in calculating the l.sub.jj term in the denominator has little or no effect on the l.sub.ij term calculation. And if the calculations are properly pipelined, once the pipeline is filled, a new term can be output on each clock cycle or every few clock cycles."
The patent application was filed on Sept. 11, 2009 (12/557,846). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,396,914&OS=8,396,914&RS=8,396,914
