Abstract

This implementation uses two read/write memory arrays 10 and 12, memory control logic 14 including polynomial character generation and checking, and a battery power source 16 with power switching control 18 which eliminate data loss due to power failures, undetected data loss, the requirement for analog power failure detection circuitry and a large reserve power supply capacity, to thereby provide a low-cost electronic equivalent to the totals accumulators conventionally used in terminals.
