Embedded Technologies

An embedded system is a computer system designed to perform one or a few dedicated functions. Embedded systems are controlled by one or more main processing cores that are typically either microcontrollers or digital signal processors (DSP’s).

CyberVision has extensive experience programming microcontrollers and DSP’s. This experience has led us to focus on algorithms, performance optimizations, mathematical modeling, and software related to engineering.

Many of our developers have a hardware Electrical Engineering (EE) education. In fact, our team’s extensive and varied scientific background helps to set us apart from other software and firmware developers.

Our embedded software development services offer low-cost development for the following domains:

Device Drivers
Industrial Controllers
Consumer Electronics
Set-Top Boxes
Telecommunication Components
Security (Biometrics, Smartcard, RFID)
Wireless Communication Equipment

Our software development teams have extensive experience working with all aspects involved in the development of embedded technologies.

For example, CyberVision solved the challenging task of porting a mobile video broadcast solution to Micrium’s µC/OS-III – a world-leading Real Time Operating System (RTOS). Micrium’s µC/OS-III significantly broadens the range of supported devices for the mobile video solution due to its ability to run on a number of processors, including ARM-based microcontrollers from Freescale, NXP, Xilinx, and Altera. CyberVision’s engineers have also solved a common problem of properly synchronizing component executions in RTOS-oriented software and are now able to take full advantage of RTOS capabilities when developing applications for Micrium's µC/OS-II and µC/OS-III.
