The thesis "Application of FPGA´s to Musical Gesture Communication and Processing" contributes two VHDL-based designs to the Digital Media Internetworking Project (see Figure 1), the current hardware project at CNMAT. The first design implements a standard MIDI-interface for receiving, synchronizing and transmitting MIDI messages. The second design uses the CORDIC algorithm for the implementation of a digital oscillator for additive synthesis. The CORDIC-algorithm is described and implemented for three architectures: bit-parallel iterative, bit-parallel unrolled (purely combinatorial and pipelined) and bit-serial iterative. The implementation of the control parameters for the oscillator presents the use of the CORDIC architecture for computing a sine function and multiplication simultaneously.
