Design, simulation and synthesis of a 32-bit math-processor

This paper presented the design and results of simulation and synthesis of a 32-bit math-processor. The emphasis was placed on implementation of floating-point arithmetic unit. This math-processor is designed in fully behavioral level by using VHDL and is able to perform floating-point operation on double precision. Also as nature of behavioral description, it is easy to convert the precision to 64-bit or more. The main ALU includes four separate ALUs: sign ALU, integer number ALU, mantissa and exponent ALU (for real number). This processor uses the micro-controlling method for control unit. This behavioral design is synthesis-able and ready for layout and fabrication or FPGA based digital circuits. Synthesis was done by Leonardo Exemplar tool and it shows this design includes 27000 standard cells and can work on 40 MHz clock in 1mum CMOS technology
