Abstract

A data processing system includes an embedded controller (100) having a core (102), a system bus, nonvolatile memory (104), and random access memory (RAM) (106). The RAM (104) has a non-overlay region (108) and an overlay region (110). The overlay region (110) may be divided into a plurality of partitions. Partitions of the overlay region (110) may be used as general purpose memory when they are not being used as overlay regions.
