An important problem in Computer Architecture and Organization course is the migration from theory to practice. Computer Architecture designs are developed to tackle this problem. This paper presents a learning activity designed to improve motivation towards learning computer architecture and organization subjects, mainly on BZK.SAU.FPGA10.1[1] micro computer architecture design. This software-based interactive system gives a visual presentation of all parts of such a micro computer architecture design; displays the states of registers; performs at the level of clock cycle, an instruction and complete program. So, when learning standard micro computer architecture subjects, students can understand executing a program instruction by instruction at the system level, where the microcomputer is considered as a black box.
