SYSTEM AND METHOD FOR OPTIMIZING MEMORY USAGE IN A UNIVERSAL CONTROLLING DEVICE

摘要

A method for optimizing memory usage in a device having a universal controlling application includes receiving into the device data for use in configuring the universal controlling application wherein the data is used to identify from within a library of command code sets stored in a memory of the device a command code set that is appropriate for use in commanding functional operations of the appliance and causing a non-identified one or more of the command code sets of the library of command code sets stored in the memory of the device to be discarded to thereby create freed space in the memory of the device.

1. A method for upgrading firmware of a device having a universal controlling application, comprising:
moving instructions and data used by a secondary processor of the device having the universal controlling application from a memory associated with the secondary processor to a set top box to provide freed memory space; storing in the freed memory space of the memory associated with the secondary processor a received firmware upgrade; validating the received firmware upgrade; transferring the validated received firmware upgrade from the memory associated with the secondary processor to a memory associated with a primary processor of device having the universal controlling application; retrieving from the set top box the instructions and data used by a secondary processor of the device; and storing the retrieved instructions and data used by a secondary processor of the device in the memory associated with the secondary processor device.
