摘要:
The present invention provides a solution to the shortcomings of the traditional two's complement system that is commonly utilized in modern computing systems and digital signal processors. The previously described shortcoming of the two's complement system are corrected in the present invention is a number system described as the negative two's complement system. In the negative two's complement system a n-bit number, A, has a sign bit, an-1, and n−1 fractional bits, an-2, an-3, . . . , a0. The value of an n-bit fractional negative two's complement number is: A = a n - 1 + ∑ i = 0 n - 2 - a i 2 i - n + 1 .
