of_mm_cv_conv_filter
Generic 2D convolution filter
Maturity simulatedTargets FPGA + ASICDifficulty EasyPriority 1
Line-buffered configurable kernel convolution for blur, Gaussian and custom filters.
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.
