In this study, the authors introduce MIPSfpga and its accompanying set of learning materials. MIPSfpga is a teaching infrastructure that offers access to the non-obfuscated Register-Transfer Level (RTL) source code of the MIPS microAptiv UP processor. The core is made available by Imagination Technologies for academic use and is targeted to a field-programmable gate array (FPGA), making it ideal for both the classroom and research. The supporting materials and labs focus on hands-on learning that emphasises computer architecture, system on chip (SoC) design and hardware–software codesign. Among other things, students learn to set up the MIPS soft-core processor on an FPGA, run and debug programs on the core in simulation and in hardware, add new peripherals to the system, understand the microarchitecture and extend it to support new features, experiment with different cache sizes and content management policies, add new instructions using the CorExtend interface available in MIPS processors, and understand SoCs in embedded systems and how they are designed and built up in layers to run complex software such as Linux.
