8 Bit Instructional Processor using FPGA

Nikita V. Nandanwar ^[2] | P. R. Thorat

Abstract: Processor is the logic circuitry that responds to and processes instructions, whereas FPGA contains an array of programmable logic blocks which can be configured to perform various functions. The main purpose of this paper is to realize functions of 8 bit processor using Spartan 6 and Opcodes are optimized in such a manner to reduce its complexity and later on can be used to reduce power consumption. Functions of processor in different modules are programmed using VHDL programming. Xilinx ISE 12.4 is used and results are verified using Isim simulator. Regarding hardware results are verified using Spartan-6 XC6LX16-CS324 board along with additional inputs and outputs by interfacing it with laptop.8085 processor was taken as reference. Instructions from Arithmetic, logical, data transfer, machine control and branching group were tested.
