fixed-point arithmetic

(computer science)
A method of calculation in which the computer does not consider the location of the decimal or radix point because the point is given a fixed position.
A type of arithmetic in which the operands and results of all arithmetic operations must be properly scaled so as to have a magnitude between certain fixed values.

There is a saturation limit of [V.sub.outd]/[V.sub.outq] which is done after [V.sub.outd]/[V.sub.outq] is again converted into 16bit fixed point numbers.
Initially, we have designed three modules which solely focus on normalization of 16bit fixed point numbers to IEEE 754 floating point numbers, floating point calculation specially addition and multiplication, and denormalization of the result into 16bit fixed point numbers.
This research implemented a simple conversion method for converting 16bit fixed point numbers to 64bit IEEE 754 double precision floating point number and vice versa.
