Binary coded decimal number division apparatus

摘要

In preparation of addresses of a quotient prediction table used in a binary coded decimal number division scheme with predetermined bits of a dividend and a divisor in binary coded decimal representation, the addresses are modified with the redundant bits. The absolute bit number for the addresses is thus decreased, whereby data quantity and hence capacity of RAM required for implementing the quotient prediction table can be significantly reduced, while satisfactory function of the quotient prediction table being assured. The apparatus for the binary coded decimal number division is implemented inexpensively in a small size.
