The design and implementation of a synthesizable model of the Serial Communication Interface and Synchronous Serial Interface, which constitutes the Port C of Motorola DSP56002 is presented in this report. They serves as a full duplex serial interface to other DSPs, processors, codecs, digital-to-analog and analog-to-digital converters and other transducers. The SCI block is able to handle a data rate of 5Mbps in Synchronous mode and 625Kbps in asynchronous mode for a 40MHz clock. It supports five word formats including a multidrop mode for multiprocessor systems. SSI provides a data rate of 10Mbps for the same 40 MHz clock. The design includes a programmable on-chip or external baud rate generator/interrupt timer for the SCI and a clock generator and frame Sync generator for the SSI. The thesis focus on arriving at a full functional description of individual blocks included with Port C from the data sheets and product users manual. From this operational description a behavioural model was developed. The structure and implementation is based on the Motorola DSP56002 with additional support for a variable data-width. The model is written completely in behavioural VHDL with a top-down approach and the model was verified and validated.
