RESUMO

This thesis presents the specification, verification, implementation, practical tests and performance analysis of a communication protocol which was developped starting from the work of Castricini and Marinangeli to the SNAP Protocol. The motivation to this work came from the communication needs of a new microcontroller named RISC16 which is under development by the University of Brasilia. To fulfill this objective, the formal description technique of finite state machine was used jointly with a explanation of the working flux, a presentation of the packet structure and the codes that implemented all the functionalities. Because all the tools for this new microcontroller were under development, a strategy was formulated. First it was implemented the communication protocol for the PIC microcontroller, and then all the generated code was translated to the RISC16. That strategy made possible the use of all mature tools to the PIC, including its simulator which helped to solve several very hard to find errors that were not visible by only inspecting the code. The translation process to the RISC16 was accomplished with only small changes in the code due to the inherent differences between the two microcontrollers.
