bitxor~ Reference

Bitwise exclusive-or-operation of floating point signals

bitxor~

Description

Use the bitxor~ object to perform a bitwise "exclusive or" operation on two incoming floating-point signals as either raw 32-bit data or as integer values. The bits of both incoming signals are compared, and the corresponding output bit will be set to 1 if the two bit values are different, and 0 if the two values are the same. The output is a floating-point signal composed of the resulting bit pattern.

Examples

Arguments

bitmask [int]

Optional

Sets the bitmask to be used by the bitxor~ object. The default is 0. An integer value can be used as a bitmask regardless of the mode; the binary representation of this integer is the bitmask.

operational-mode [int]

Optional

Specifies whether the floating-point signal or floating-point value will be processed as a raw 32-bit floating-point value or converted to an integer value for bit inversion. The modes of operation are listed below.

0: Treat floating-point signal input as a raw 32-bit value (default).
1: Convert the floating-point signal input to an integer value.

Attributes

mode [int]

Specifies whether the floating-point signal or floating-point value will be processed as a raw 32-bit floating-point value or converted to an integer value for bit inversion. The modes of operation are listed below.

0: Treat floating-point signal input as a raw 32-bit value (default).
1: Convert the floating-point signal input to an integer value.

Common Box Attributes

Messages

int

Arguments

bitmask [int]
In right inlet: An integer value can be used as a bitmask when supplied to the right inlet of the bitxor~ object, provided that the proper mode is set.

bits

Arguments

bitmask (32 ones or zeros) [list]
In left inlet: The word bits, followed by a list containing 32 ones or zeros, specifies a bitmask to be used by bitxor~. Alternately, a bitmask value can be set by using an int value in the right inlet.

signal

In left inlet: The floating-point signal is compared, in binary form, with the floating-point signal in the right inlet. The signal can be treated as either a floating-point signal or as an integer.
In right inlet: The floating-point signal to be compared with the signal in the left inlet. The signal can be treated as either a floating-point signal or as an integer.
The raw floating-point signal bit values are expressed in the following form:
<1 sign bit> <8 exponent bits> <23 mantissa bits>

Output

signal

The two floating-point signals or ints received in the inlets are compared, one bit at a time. A 1 is output if the two bit values are different, 0 if they are the same. The output is a floating-point signal composed of the resulting bit pattern.
