Abstract

This paper presents a UML 2.0 based design flow for real-time embedded systems. The flow starts with UML 2.0 application, architecture and mapping models for our TUTWLAN terminal with its medium access control protocol. As a result, the hardware/software implementation on Altera Excalibur FPGA is achieved. Implementation utilizes eCos real-time operating system, and hardware accelerators for time-critical protocol functions. The design flow is prototyped in practice showing rapid UML 2.0 application model modification, real-time protocol processing in an image transfer application, and execution monitoring.
