WebNov 27, 2024 · Likewise, ram configs below 32 might be better served by a DMEM of size 32. These are because a SLICEM can be a 1 bit, 256 depth RAM, or a 6 bit, 32 depth RAM. (the latter is because the SLICEM is 4 LUTs with a shared write address, but 3 independent read addresses. It also has f7/f8 muxes to allow 2-4 LUT outputs to be quickly muxed.)
