Yamaha FM-Synthesis in VHDL

a FM-Synthesis module in VHDL
	DSP Module	A VHDL-implementation of my cyclic synthesis algorithm is used for FM-like sound synthesis in my audio DSP. Unlike the C/ASM-version the chaining of the module is variable so the sequence can be exchanged. Up to 6 FM-modules are used to emulate the typical FM-modulator chain known from Yamaha-DX-Synthesizers. With the Spartan FPGA @50 MHz, 1024 voices can be achieved @ 48kHz. For best operation the sampling frequency should be shifted to at least ratio 8 for 4 operators and ratio 16 for 8 operators. Due to limitation of the FPGA only 6 operators are available.
