Gamma and tone curve LUT
Maturity simulatedTargets FPGA + ASICDifficulty EasyPriority 1
Piecewise-linear or LUT-based gamma and transfer curve application per colour channel.
Simulated. The RTL is lint clean and passes its self-checking testbench against a reference model in simulation. It has not been run on an FPGA board or in silicon.
