Color display using auxiliary memory for color information |
摘要 |
Method and circuit for controlling the color of dot elements in a raster scan display having a data memory for storing the state (on or off) of dot elements which are mapped onto the raster scan display and a smaller auxiliary memory for storing color information. The color information stored in a location of the auxiliary memory specifies the color of a plurality of contiguous dot elements so that the auxiliary memory can be much smaller than the data memory. The contiguous dot elements whose color is specified by a location in the auxiliary memory form a block which can be arranged so that the address bits to the auxiliary memory form a proper subset of the address bits to the data memory.
