Microprocessor Firmware Update Inventory Model

Microprocessor-based systems are used in many applications of modern telecommunications. The controlling program of most microprocessor systems is stored in firmware which is usually coded into erasable programmable read-only memory chips (EPROM). As new services are implemented, there is a continuing need to update the firmware, a potentially expensive process. In this paper, a method is presented for determining the resources necessary for updating EPROM firmware from a centralized location by using a rotating inventory scheme.
