- filter: ideas and sketches for a 1/10 (samples per clock cycle) to 2/1 interpolator cascade, analysis of other interpolator approaches, comparison of CIC/HBF/FIR, CIC droop compensation filter
- cic: ideas for CIC implementations and tests of interpolation modes
Precompiled bitstreams are available under releases.
With vivado and a vivado-compatible JTAG dongle, to load (volatile) a bitstream onto the FPGA, use:
vivado -mode batch -source load.tcl -tclargs build/phaser.bit
To flash it, use:
vivado -mode batch -source flash.tcl -tclargs build/phaser.bit
With openocd and a JTAG dongle that fits the connector and has openocd support it
should also be possible to load and flash using the xc7a support and the jtagspi proxy bitstreams.
