Embedded code memory size reduction in asynchronous mode transfer devices

摘要

A system for reducing the memory requirements of an ATM device utilizing one or more temporary code uploads to bring needed portions of application code into the memory of the ATM embedded system on a temporary basis. The present invention functions to divide the code necessary for operation of the ATM device into two categories: (1) application code that is seldom used or code used only once and (2) all other application code. The application code that is seldom used or used only once is removed from the memory of the ATM embedded system and placed in a software storage device external to the system. This serves to significantly reduce the memory requirements of the ATM device, by as much as 40% in come cases depending on the size of the application code portions.
