Design av applikationsspecifik mikrocontroller

This master thesis describes the process of designing an application specific microcontroller. The microcontroller should be used in a demonstrator for a protocol processor. The demonstrator should show the possibilities to access high speed networks with small processor cores. The demonstrator should be able to receive and playback an audio stream. Some of the tasks in the demonstrator should be performed by the microcontroller. It should handle ARP requests, buffer handling and sending audio samples to a stereo codec. Behavioral models for these applications were constructed and used to design the instruction set for the microcontroller. An instruction set simulator was constructed. It was used to verify that the instruction set was sufficient to achieve functional coverage. The micro architecture for the microcontroller was designed and implemented in VHDL. This implementation was verified by simulation. The test vectors used during simulation were mainly randomly generated
