Re: Render characters

Another approach (taken by the Xerox DLion) is to have a separate
instruction just for displaying characters.  This instruction, called
(appropriately) "TextBLT", knows about the font table formats and
specialized for displaying rectangular blobs of text.  TextBLT is also
implemented in microcode, on the DLion's AMD2900-based CPU.
