A high speed operation system intended for data closed for operations such as floating-point data in which a desired final operational result is obtained by converting the data to the one for which an arithmetic and logict ( ALU ) can be simplified (the number of elements and gate delay time, etc. are reduced ) with an encoder .PHI. by executing a series of operations for the encoded data and, by restoring the obtained result to the original data representation with a decoder, ?.

Why it's free to use
- Filed December 25, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 25, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 25, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
