A Note on Base –2 Arithmetic Logic
C. K. Yuen · IEEE Transactions on Computers · 1975
Circuits for performing arithmetic operations using base –2 representations are considered. Study of the counting process leads to a negative binary up-down counter and new simple methods for positive-negative base conversions. The advantage of employing carry-borrow rather than carry-only during additions is pointed out. Certain special features of negation, arithmetic shift, multiplication, and division in base –2 are described.
