Abstract The most significant bits of the input digital word address a read-only memory (ROM). Stored at each ROM address is a table of instruction words one instruction, word for each bit in the output word. The instruction words direct a switch to select each bit for the output word from a choice of 1, 0, or an input bit. The instruction words also command selective bit inversion and selective inclusion of the bit in a parity check. Implementation of the translator with commercially available hardware is described.
