Abstract (in Japanese) (See Japanese page) 
(in English) It is necessary to predict by high accuracy the results of the branch commands so as not to obstruct the speed-up of microprocessors by the pipelining. Under the condition of not putting the limitation on the computer resources Kise and Iwata did the branch prediction with high accuracy by means of the technique of Jacquet et al. which is based on the pattern matching. It is theoretically guaranteed that the technique of Jacquet et al. is asymptotically optimal for stationary mixing sources. On the other hand, Ota and Morita have proposed a modeling technique for the processing that corresponds to the pattern matching at a linear computing time by using the structure that is called an anti-dictionary tree that consists of a suffix tree and reversed MF links on it.
In this research, the technique of \cite{OTAMORITA} is applied to
the branch prediction to obtain the same results as with Jacquet et al. at a practical execution speed. As results of the experiments, the execution times are shortened from 1/50 to 1/4600 with hardly more inferior prediction accuracy than Kise and Iwata.
