The first semester project - deadline for submission is week 7 Complete assignment of the first semester project: 01_semester_project.pdf
Project evaluation:
It is necessary to achieve at least 6 points (inclusive) for the successful submission of the project. The use of C language compiler mips-elf-gcc is allowed, same as the program mips-elf-as for translation from symbolic address language to machine code and for relocation and completion of binary code linker mips-elf-ld can be used.
The Debian packages can be download from binutils-mips-elf_2.34-1_amd64.deb and gcc-mips-elf_10.1.0-1_amd64.deb
Next commands can be used for installation
sudo dpkg -i Downloads/binutils-mips-elf_2.20.51-1_amd64.deb sudo dpkg -i Downloads/gcc-mips-elf_4.4.4-1_amd64.deb
You can install packages through repository as well
wget -qO - http://pisa-virt.felk.cvut.cz/repos/apt/debian/pisa-virt-reprepro.pub | sudo apt-key add - echo deb http://pisa-virt.felk.cvut.cz/repos/apt/debian unstable main >/etc/apt/sources.list.d/pisa-virt-debs.list apt-get update apt-get install qtmips
For Windows use mips-elf-gcc-i686-mingw32.zip.
For MacOS binutils-mips-elf_2.34_macos.zip and gcc-mips-elf_10.1.0_macos.zip. Extract on filesystem root.

You can base your data and program memory modules on the following Verilog code fragment - take it as an inspiration which is sufficient for our purposes.:
module dmem (input clk, we, input [31:0] a, wd, output [31:0] rd); reg [31:0] RAM[0:127]; assign rd = RAM[a[7:2]]; // word aligned always@(posedge clk) if(we) RAM[a[31:2]] <= wd; endmodule
module imem (input [7:0] a, output [31:0] rd); // The "a" is the address of instruction to fetch, what // for our purpose can be taken from ProgramCounter[7:2] reg [31:0] RAM[0:255]; initial $readmemh ("memfile.dat",RAM); assign rd = RAM[a]; // word aligned endmodule
