Reduced energy consumption is one of the most important design goals for embedded application domains like wireless, multimedia and biomedical. Instruction memory hierarchy has been proven to be one of the most power hungry parts of the system. This paper introduces an architectural enhancement for the instruction memory to reduce energy and improve performance. The proposed distributed instruction memory organization requires minimal hardware overhead and allows execution of multiple loops in parallel in a uni-processor system. This architecture enhancement can reduce the energy consumed in the instruction and data memory hierarchy by 70.01% and improve the performance by 32.89% compared to enhanced SMT based architectures.
