Single Cycle CPU: Our Project of CS202 2023 Spring: Computer Organization, SUSTech.

We use FPGA MINISYS 1-A to implement part of the MIPS32 instruction set. Support simple bit operations and binary addition, subtraction, multiplication, and division functions.

Final score: 121/100.

You can check docs folder to see project requirement. And our project report in Chinese.

• ASM_Minisys-1A : MIPS assembly file and binary file ,check Readme in this folder for more information.
• CPU_Verilog : Verilog file for this project.
• docs : Project requirement and our report.
• EDA_Xilinx : Some files for Xilinx EDA Vivado, check Readme in this folder for more information.
• unused : Some unused files, including Verilog file for onlinejudge test.

Use Vivado, select the device xc7a100tfgg484-1.

You can load bitstream file directly, or:

1. Add the IP core in EDA_Xilinx/
2. The RAM and ROM IP core loads the .coe file in EDA_Xilinx/ respectively
3. Add the Verilog file in CPU_Verilog/
4. Add the pin constraint file
5. Use VIvado to simulate, synthesize, and then generate bitstream files

For example, if you want to do scene 1 test case 001:

1. Press Program Restart Button
2. Press UART Start Reprogram Button, then use UART to transmit sc1_new_version.txt
3. Press Program Restart Button again to start the new program
4. Let "Test case ID Input" low 3 bits switch be 001 (1 means on), then press Input confirm button
5. Let Binary Value Input low 8 bits be the number 1 you want to input, then press Input confirm button, the Binary Value Input display will show the number 1 in high 8 bits.
6. Let Binary Value Input low 8 bits be the number 2 you want to input, then press Input confirm button, the Binary Value Input display will show the number 2 in low 8 bits.
7. Press Input confirm button, then the led or keyboard will show the result.
