You could use faster ram and perform a read, insert the bit and then write back the modified byte. You'd probably want to store each plane in a 64kx8 dram though, so you'd need 3 copies of that logic. When outputting you get 8 pixels for each memory read & with this scheme you'd continue to do so, if instead you use the extra bits in the ram chip for individual planes then you'll need memory that is 8 times faster.Received on 2018-06-26 14:00:04
