Abstract:

Real-time image transmission is a key discipline for a lot of applications like computer vision and image processing. This paper introduces the Linux device driver architecture, followed by a detailed analysis of the device driver for a PCI-interfaced real-time image transmission card under Linux. The analysis focuses on some key parameters that influence the transmission speed most. The speed of the card under Linux and Windows are compared.

Key words: Linux, Real-time PCI, Device-driver
