Abstract
Non-power-of-two Gray-code counters, including modulos 10, 12, 14, and 22 are disclosed, along with a sequencing method they employ. Each counter includes a register for storing an N-bit, e.g., 4-bit, Gray-code count. The count is converted to binary code by a Gray-to-binary-code counter. The resulting binary count is incremented by an N-bit incrementer that skips certain binary values by toggling least-significant bits in unison when indicated by certain most-significant binary bits. The result is converted to Gray-code by a binary-to-Gray-code translator. The translated result is stored in the register as the next count. An algorithm is disclosed for designing such a Gray-code counter for any even modulo. The modulo is expressed as a sum of positive and negative terms, each term being a power of two. The exponents of the terms determine the counter design.
