Low-power consumption architecture for embedded processor

A low-power processor architecture is described dedicatedly for embedded application programs by means of an object code compression approach. This approach unifies duplicated instructions existing in the embedded program and assigns a simple number to each distinct instruction. An instruction decompressor is constructed in an embedded processor, which is to generate an object code from a compressed object code (pseudo code) input. A single-chip implementation of this decompressor together with a processor core can effectively reduce the bandwidth required for the I/O interface. Experiments are applied to an embedded processor ARMG10 to demonstrate the practicability of the proposed approach.
