ABSTRACT
Microcomputer principle and assembly language curriculum development up to now, the research field of development and change constantly, at the same time with many courses related to discuss problems exist. To improve the quality of teaching, must first clear the primary teaching content of courses. Assembly language and high-level language does not have different portability, Z80 to 6502, and then to 8086/8088 and now Pentium how are and their supporting assembly language. Due to 8086/8088 of the typicality, so most of microcomputer principle and assembly language teaching are given priority to with 8086/8088, at the same time in the process of teaching by introducing some new high-grade machine the expansion of CPU instructions and programming methods, such as the proportion of base indexed addressing mode, and 32-bit programming, etc.
