24-bit Stereo Audio DAC for Raspberry Pi
Expiremental Speech Recognition System using VHDL & MATLAB.
SoCFPGA: Mapping HPS Peripherals, like I²C or CAN, over the FPGA fabric to FPGA I/O and using embedded Linux to control them (Intel Cyclone V)
A RISC-V SoC ( Hbird e203 ) on Terasic DE10-Nano
Spectrum analyzer system using a 512-point FFT, in a Cyclone IV FPGA. Reads i2s audio from the codec and then does all FFT/VGA functions. Nios just reads the FFT result and draws the display bars. VGA frame buffer on-chip. VGA signals generated on-chip. See the included video files to watch it in action.
