In this paper, I observed that Gemmini includes the im2col module. The Rocket core consumes too many clock cycles on im2col. I need a more efficient way to execute im2col. Does the current Gemmini support the im2col function?

The im2col module was basically replaced by the LoopConv.scala module, which is used by default by tiled_conv_auto. It should be used by default by resnet50.c and mobilenet.c, if you want to see examples
