The benefits of learning assembly language can help programmers to grasp the characteristic and limitation of computer in order to develop more efficient programs. ARM and NIOSII are two of the most commonly used processors in embedded systems. So many people use ARM platform to learn assembly language and hardware architecture. However, there are many instructions in the instruction sets of ARM or NIOS II, which might be difficult for beginning students to learn. This study is about the design of a course on microprocessor using a soft processor LC-3 that runs on an FPGA platform called DE0 from Altera. I/O devices of DE0 board and Lego NXT devices can be driven by an LC-3 core. Student can use LC-3 assembly language to program their applications to control I/O devices. This should add more fun to learning assembly language programming and computer organization, and flatten the learning curve for students.
