Introduction

Aim

The aim of the project is to aid first year and second year students with their learning of digital systems and computer architecture in Digital Systems courses. The outcome of the project is to create a set of tools as a teaching aid for the laboratories of these Digital Systems courses. Motivation

Use Case Scenarios

This section describes the scenarios of how and where the teaching aid will be used.

1st Year Digital System course laboratories

Students will be provided with an example assembly language program. They will simulate the program on the Host PC and observe the execution of the instructions. They can modify the program. The students will run the example assembly language program on the FPGA board and observe the outcome. There will be specifications provided in the lab which require the students to design logic blocks to connect the disARMed processor with the peripheral blocks such as the LEDs.

Figure 1.2 shows an example where the students are required to connect the disARMed microprocessor with the LEDs peripheral block with the address decoder coloured in blue.

2nd Year Digital System course laboratories

Second year students will create their own assembly language programs and simulate it on the Host PC. They will observe how each instruction is executed, the datapath each instruction follows, and the change in values in the registers and memory.

The students will download their assembly program onto the Basys-2 FPGA board and run it with the disARMed microprocessor. They will observe the interactions of the microprocessor with the peripheral blocks on board the Basys-2 FPGA board. In addition, students will explore the Verilog code of the disARMed microprocessor. Students will be given an incomplete disARMed microprocessor where they have to design and implement the missing module.

For example, the microprocessor may be missing the ALU component and students will be required to design their own ALU as shown below (in blue rectangle).
