Module ciphercore_base::ops

Implementation of several custom operations. A custom operation can be thought of as a polymorphic function, i.e., where the number of inputs and their types can vary.

Modules

adder

Binary adder that adds two bitstrings.

clip

Clip function that returns a given value if it is inside of the interval [0,2^k] and clips values outside this interval to its edges.

comparisons

Various comparison functions for signed and unsigned integers including greater-than, less-than, greater-than-equal-to, less-than-equal-to, equal, not-equal.

inverse_sqrt

Inverse square root approximation via the Newton-Raphson method.

min_max

Minimum and maximum operations. They operate on unsigned integers represented as bitstrings.

multiplexer

Multiplexer (Mux) operation that takes three inputs a, b, c and returns b if a is 1 or c if a is 0.

newton_inversion

Multiplicative inversion via the Newton-Raphson method.

pwl

sorting

Sorting of an array

taylor_exponent

Exp(x) approximation relying on Taylor series expansion.
