Project Description

• We have implemented a RISC-V single cycle processor.

• We have used many object oriented programming concepts and implemented a processor with alu , control unit and memory mocking the working of of a processor in exact same way which makes our code much more readable and intuitive. All of this combined with a gui.

• First we created a window gui with help of tkinter and linked the button commands to that of the processor.

• FETCH, we have a method of processor object fetch, it fetches the instruction from the data.mc file

• DECODE, a object of Instruction is created and we get access to all attributes of Instructions.

• EXECUTE, ALU does its calculation and is used to determine the value of muxselect of the mux deciding PC, and the data is made available to memory.

• Memory Access, Memory is written or accessed according to the type of instruction.

• Write Back, in the write back stage we are writing the value in destination register.
