• Basic Nios II system for the DE2
  A simple example of a very basic Nios II system for the DE2 development board. This Nios system includes the following components:
  - Nios CPU
  - SDRAM
  - SRAM
  - on-chip memory
  - LCD display
  - 17 Red LEDs
  - 9 Green LEDs
  - 8 7-segment displays
  - 17 switches
  - 4 push buttons
  This example includes four separate C programs that will run on this Nios system.
  Equipment requirements: Quartus II v7.2, Nios II v7.2, DE2 board.
  Instructions for configuring the FPGA and executing the compiled C code directly.

• LCD Controller
  The basics of controlling an LCD display. The FSM acting as the controller is implemented in VHDL. Documentation for the LCD is found here.
  
  
• I2C Master Controller
  A basic I²C master bus controller to communicate with a real-time clock slave using the I²C bus. A FSM acting as the controller is implemented in VHDL. The article describing this implementation is found here. Documentation for the I²C bus specification is found here.

• The MIPS processor
  from the book Computer Organization and Design, 3^rd Edition, by Patterson and Hennessy. This is an implementation of the multicycle MIPS processor based on the datapath of Figure 5.28 on page 323 and the control unit of Figure 5.37 on page 338. The instructions implemented are: ADD, ADDI, SUB, AND, OR, SLT, LW, SW, BEQ, JUMP, OUTPUT, and HALT. The last two instructions are not from the MIPS processor. The sample program will count down from 10 down to 0.
  Equipment requirements: Quartus II, UP2 board.
