Superscalar Reduced Instruction Set Computer

Course Project - CS 683 - Advanced Computer Architecture

Course Instructor - Prof. Virendra Singh

This repository contains our design of a 2-way out-of-order superscalar architecture and consists of all the Design Documents, Testbenches and Hardware Descriptions in VHDL

Instruction Set Architecture Specification

It is the same as 17 instructions supported by the IITB-RISC-22, their encoding can be found in the Problem Statement.

Assembler

An assembler for the IITB-RISC-22 was designed in Python to convert any input program stored as .asm into a sequence of machine level 16 bit word instructions stored in ./source.bin . The source code for it can be found in ./assembler.py. The assembler also provides support for both inline and out of line comments for documentation to be present in the .asm file.

To assemble the code for a file called code.asm in the same directory as assembler.py can be done in the following way.

python assembler.py code

Bootloader

An software emulated bootloader for the IITB-RISC-22 was designed in Python to dump the binary file into the memory of the IITB-RISC-22. The source code for it can be found in ./bootloader.py . It takes as input the binary file source.bin and loads the instructions into the file ./final/rom.vhdl.

To load the binary file source.bin into memory do the following

python bootloader.py code
