| 摘 要： | 本文研究了用32×8乘法器完成32×32乘法累加器的算法实现。将32×8乘法器计算出的结果作为下一次32×8乘法计算的部分积来完成4次32×8乘法结果的累加操作,减小了硬件开销。同时为满足累加操作的需要,对Booth算法的补偿常数的数值也做了修正。

| Abstract: | In this paper, an algorithm and implementation of 32(32multiplier with 32(8multiplier -accumulator is presen ted.The 32(32multiplication is achieved by 4times 32(8multipli-cation.The result of 32(8multiplication serves as a part ial product of the next 32(8operation when the result of four su ch multipli cation is accumulated.A mo dified fixed number is pre-sented for sign extensio n preventuon. |
