System and method for optimizing bill of material cost and power performance of platform system-on-chip for battery management system
The present invention provides a system and method for optimizing BOM cost of platform SoC for Battery management system. The system ( 100 ) comprises a sensor ( 101 ), coupled with the device to receive input physical parameters Temperature, Voltage and current and a CPU with SIMD extensions without saturation logic in the instruction set and floating-point unit, wherein Battery management module is implemented ( 101 ). Using CPU with SIMD extensions instead of DSPNLIW 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 in either case (Battery management implementation on CPU, DSP ISA) is the same, thus giving value additions to platform SoC designers and makers.
