8位二进制数乘法器VHDL实现8位二进制数乘法器设计，乘法通过逐项移位相加原理来实现，从被乘数的最低位开始，若为1，则乘数左移后与上一次的和相加；若为0，左移后以全0相加，直至被乘数的最高位。 -8-bit binary multiplier VHDL 8-bit binary multiplier design, multiplication by itemized shift sum principle, starting from the least significant bit of the multiplicand 1, the multiplier the left after the last and addition　if it is 0, to 0 after adding the left until the most significant bit of the multiplicand.
