Abstract

See full text

Apparatus and method are described for a data processing device. The data processor includes features suitable for executing a software virtual machine. The data processor provides an instruction set that supports object-level memory protection suitable for high speed operation. Memory control logic is provided to accommodate a configuration having relatively less random access memory (RAM) as compared to re-programmable, nonvolatile memory, and to improve access to the re-programmable, nonvolatile memory.
