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. |
