Memory-CPU Size Optimization For Embedded System Designs

Entire systems embedded in a chip and consisting of a processor, memory, and system-specific peripheral hardware are now commonly contained in commodity electronic devices. Cost minimization of these systems is of paramount economic importance to manufactures of these devices. By employing a variable configuration processor in conjunction with a multi-precision compiler generator there are situations in which considerable system cost reduction can be obtained by synthesizing a CPU that is narrower than the largest variable in the application program.
