Cache memory for arithmetic computational operations with partial result of administration in the case of partial operand by means of tuning

摘要

An arithmetic device having a cache for performing arithmetic operations is provided. The cache stores previously performed resultant data and operand for an arithmetic operation and upon receiving a same operand to be operated upon, the corresponding stored resultant data is output, bypassing the arithmetic processing and operation by the processor. The device having the cache is also configured for outputting a partial resultant output for a partially matched operand.
