Abstract: The present invention provides a system and method for optimizing power consumption in Multimedia Signal Processing in mobile devices. The system comprises a Media (speech, audio, image, and video) codec encoder module, a Media codec decoder module (106) and pre-processing and postprocessing (filtering, deblocking filter, Analytics, person detect, keyword/keyframe spotting) modules modules. The pre-processing and post-processing modules are implemented on a DSPNLIW processor, while the Media encoder and decoder modules are implemented on a CPU with SIMD extensions. This pipeline (asynchronous RPC, non-blocking) implementation of modules in multi-core reduces current consumption in the SoC by up to 50 percent compared to an implementation of the modules in a multiple CPU/DSP/VLIW core with synchronous RPC (blocking). The significant reduction in current consumption of the modules enables reduction of power consumption in the Multimedia processing use case.

Abstract: The present invention provides a system and method for optimizing BoM cost of platform SoC in mobile devices. The system (100) comprises a CPU with SIMD extensions wherein video codec encoder/decoder module is implemented (101), and another CPU with SIMD extensions instead of DSP/VLIW core wherein post-processing filtering module (Deblocking filter) (102) module is implemented. Replacing DSP/VLIW core in platform SoC helps in lowering the BoM cost and the inventive steps helps in achieving bit-exact results overcoming the limitations of CPU ISA as against DSP ISA. The power consumed is either case (deblocking filter on CPU, DSP ISA) is the same, thus giving value additions to platform SoC designers and makers.

Abstract: The present invention provides a system and method for optimizing power consumption in voice communication in mobile devices. The system comprises pre-processing modules, a speech codec encoder module, a speech codec decoder module and post-processing modules. The pre-processing and post-processing modules are implemented on a DSP/VLIW processor, while the speech encoder and decoder modules are implemented on a CPU with SIMD extensions. This pipelined implementation of modules in multi-core reduces current consumption in the SoC by up to 50 percent compared to an implementation of the modules in a single DSP/VLIW core. The significant reduction in current consumption of the modules enables reduction of power consumption in the talk time.

Abstract: The present invention provides a system and method for optimizing power consumption in mobile devices. The system comprises a speech codec encoder module and a speech codec decoder module. The number of CPU/DSP/VLIW processor cycles taken to encode and decode the speech signals are significantly reduced to draw lower current by the mobile device. The significant reduction of processor cycles in the speech codec modules enables reduction of power consumption in the talk time. Thus, the invention provides a simple method of optimizing power consumption by reducing number of processor cycles to compress/decompress speech signal of the speech codec modules in mobile devices.
