WebFixed-Point Arithmetic Addition and subtraction Whenever you add two fixed-point numbers, you may need a carry bit to correctly represent the result. For this reason, when adding two B-bit numbers (with the same scaling), the resulting value has an extra bit compared to the two operands used. a = fi (0.234375,0,4,6); c = a+a WebFor that reason,we have explored Floating point unit, have different operations almost all of the algorithms implemented in FPGA (Field programmablegate array) kit by use of Xilinx ISE compiler & algorithm are design in VHDL language.Main advantage of floating-point representation is that it can support a much wider range of values, over fixed ...
