| Zusammenfassung: | To provide a technique capable of suppressing an increase in access time.SOLUTION: Arithmetic devices 100, 100B each include: an arithmetic unit 11 that executes a neural network model to perform arithmetic processing; a cache unit 12 in which data used by the arithmetic unit is stored; a calculation unit 31 that calculates a hit rate, which is a ratio at which the data used by the arithmetic unit is stored in the cache unit; a determination unit 32 that determines a compression rate according to the hit rate and a predetermined target hit rate; and a compression unit 33 that compresses the data stored in the cache unit at the compression rate.SELECTED DRAWING: Figure 1
【課題】アクセス時間が長くなることを抑制できる技術を提供する。【解決手段】演算装置１００、１００Ｂは、ニューラルネットワークモデルを実行して演算処理を行う演算部１１と、演算部が用いるデータが格納されるキャッシュ部１２と、演算部が用いるデータがキャッシュ部に格納されている割合であるヒット率を算出する算出部３１と、ヒット率と予め定められた目標ヒット率とに応じて圧縮率を定める決定部３２と、キャッシュ部に格納されるデータを圧縮率で圧縮する圧縮部３３と、を備える。【選択図】図１ |
