    • A signed multiplication method and a corresponding device for multiplying a first multiplicand with a second multiplicand. The device stores the first multiplicand in a first register as a first vector of at least one respective digit and storing the second multiplicand in a second register as a second vector of at least one respective digit, each digit having a pre-determined number of bits. The method further converts the digits of the first vector and the second vector to corresponding digits of one bit less each than the pre-determined number of bits. A processor effects signed multiplication of the multiplicands.
    • 一种有符号乘法方法和用于将第一被乘数与第二被乘数相乘的相应装置。 设备将第一被乘数存储在第一寄存器中作为至少一个相应数字的第一向量,并将第二被乘数存储在第二寄存器中作为至少一个相应数字的第二向量,每个数字具有预定数量的位 。 该方法还将第一向量和第二向量的数字转换成比预定位数少一位的相应位数。 处理器对被乘数进行带符号乘法。
