Function
Converts the specified double-precision floating-point
data (64 bits) to 16-bit signed binary data and outputs
the result to the destination word.
Converts the specified double-precision floating-point
data (64 bits) to 32-bit signed binary data and outputs
the result to the destination words.
Converts the specified 16-bit signed binary data to dou-
ble-precision floating-point data (64 bits) and outputs
the result to the destination words.
Converts the specified 32-bit signed binary data to dou-
ble-precision floating-point data (64 bits) and outputs
the result to the destination words.
Adds the specified double-precision floating-point val-
ues (64 bits each) and outputs the result to the result
words.
Subtracts the specified double-precision floating-point
values (64 bits each) and outputs the result to the result
words.
Multiplies the specified double-precision floating-point
values (64 bits each) and outputs the result to the result
words.
