We introduce the notion of two-valued digit (twit) as a binary variable that can assume one of
two different integer values. Posibits, or simply bits, in {0, 1} and negabits in {-1, 0} …

Common criteria (CC) provides only the standard for evaluating information security product
or system, namely target of evaluation (TOE). On the other hand, SSE-CMM provides the …

Technology in general and the Internet in particular have often been seen as the" great
equalizer" in that it provides a level playing field for all individuals in the society in terms of …

Hybrid-redundant number representation has provided a flexible framework for digit-parallel
addition in a manner that facilitates area-time tradeoffs for VLSI implementations via arbitrary …

This paper presents a ternary (4: 2) compressor, which is an important component in
multiplication. However, the structure differs from the binary counterpart since the ternary …

Signed digit (SD) number systems support digit-parallel carry-free addition, where the sum
digits absorb the possible signed carries in {− 1, 0, 1}. Radix-2h maximally redundant SD …

Redundant representations play an important role in high-speed computer arithmetic. One
key reason is that such representations support carry-free addition, that is, addition in a …

This paper aims to fill the gap between theoretical studies of redundant number
representation dealing with digit-level algorithms, without considering circuit-level details or …

Signed-digit (SD) numbers generalize traditional radix numbers by allowing negative digits
within a certain range. Typically, this leads to redundant number representations that can be …

Signed digit number systems provide the possibility of constant-time addition, where inter-
digit carry propagation is eliminated. Carry-free addition for signed digit number systems is …
