Embedded Systems:
Our embedded product design service includes developing products using operating systems
such as QNX, Linux, and Windows CE. Embedded software is typically programmed in C/C++,
however in some cases assembly language is used for those critical routines and tasks.
Hardware design elements such as FPGAs, Microprocessors, Microcontrollers and
Digital/Analog RF circuitry design are all utilized during project definition and implementation.
Below is a partial listing of some of our past designs.
