[meta] two-tone demo with kc705+ad9154

[jordens]

• publish https://github.com/m-labs/phaser
• RTIO spline interpolators (frequency, phase, amplitude, offset) for parallelized DDS core
• RTIO spline data kernel/runtime support
• RTIO spline data handling (knot generation, indexing, scaling, embedding at compile time)
• Two regular speed (fDATA/4 or fDATA/8) a,f,p-interpolating DDS cores
• Latency matching of all RTIO channels
• best effort attempt to synchronize DACs on FMC cards
• DRTIO DRTIO #562

DRTIO and DAC synchronization will be done on Sinara directly. The two-KC705 SAWG demonstration plan will not be pursued.
