Computer Use: The students use a computer to execute a RISC assembly language simulator that is used for various assembly language programming projects, and/or use a computer to run logic design software that is used to design various processor modules.

Laboratory Projects: The students may be given hardware and/or software design assignments:

Software:

Assembly language programming assignments may be given to familiarize the students with the RISC assembly language and to reinforce certain architecture concepts. Example assignment:

  • Floating point arithmetic: design a routine that emulates floating point addition or multiplication.

Hardware:

Various processor modules may be implemented at the gate level. Example projects include:

  • Design a simple ALU to support a RISC instruction subset.
  • Design a simple control unit to support a RISC instruction subset.
  • Design a pipeline hazard detection unit. 
  • Design a pipeline forwarding unit.

Engineering Design Statement:
The course emphasizes techniques for designing processors, from the architecture level to the gate level. In projects, homework assignments, and exams students are presented with problems that require them to explore various approaches to processor design, to choose between alternatives, and to justify solutions based on performance, cost, and/or complexity considerations.
