Implementation of a Serial Communication Interface for a Signal Processor

Abstract: The purpose of this thesis was to implement a serial communication port model for a digital signal processor. It is a behavioral model, developed using VHDL, that is instruction comparisable to the Motorola digital signal processor DSP 56002. It supports five different data transfer modes and provides a programmable baud rate generator. This report starts out by giving a description of the external port, port C, the pin control logic and general purpose functionality. Then a more detailed description of the three pin dedicated serial communication interface is presented, the different operating modes and the baud rate generator are described.
