技術說明

【中文】一種乘積累加裝置及其方法。乘積累加裝置包括乘積產生器、多個寄存器、乘積化簡器以及加法器。乘積產生器對被乘數與乘數進行乘積運算，以產生2N-1行的乘積結果。乘積化簡器用以將多個寄存器中的部分寄存器的資料附加於乘積結果中的各行，以產生2N-1行的附加結果。乘積化簡器並依據附加結果中各行的行高，來對附加結果進行化簡運算，以得到化簡後結果。以及，乘積化簡器依據化簡後結果來更新該些寄存器中的資料。加法器依據累加信號以對多個寄存器中的資料進行累加運算，以產生乘法累加運算結果。 【英文】A multiplication accumulating device and a method thereof are provided. The multiplication accumulating device includes a product generator, a plurality of registers, a product reducer, and an adder. The product generator performs a product operation on the multiplicand and the multiplier to generate a product result of 2N-1 columns. The product reducer is used to append data from a portion of the plurality of registers to the columns in the product result to generate an additional result of 2N-1 columns. The product reducer performs a reduction operation on the additional result according to the column height of each column in the additional result to obtain the reduced result. And, the product reducer renews the data in the plurality of registers according to the reduced result. The adder adds the data in the plurality of registers according to an accumulated signal to generate a multiplication and accumulation operation result.
