Re-architecturing Compressed audio decoder for Car Radio
  Re-engineering / Reverse Engineering
Ported the driver and application firmware to support new CD mechanism and fix the task scheduling problem – 68HC11KS2 based Car Radio
Driver and application firmware porting from 68HC11 to ST92F120 processor to enhance the product performance and reduce overall product cost.
Cryogenic temperature control system – Replicated the functionality of the PCI add-on card based control system card to a standalone dual MCS51 processor based product which helped the customer to achive better cost performance and serviceability.
IBOC module interface with Car radio – Documented the complete interaction sequence between the Radio, DSP and the IBOC, which helped a lot in improving the performance of the overall entertainment system.
