Performance Analysis of Embedded Linux ATM for MPC8260 and Derivatives

Framework to Port Linux Kernel on PowerPC Based Embedded System Used for Telecom Application - IPBTS

“…Porting linux operating system to a new hardware board works like an embedded system doesn't need to be hard but the whole development process is some sort of complicated, so it costs much more time to master the source code of kernel for different architectures and whole development flow. In the future this embedded system performance is evaluated [20], analysed and can be tuned to design a customized embedded system for any other telecom application.…”

“…The objective of the transmit (Tx) interrupt handling routine within the device driver is to empty the Tx buffers so that they can temporarily store new traffic that is going to be transmitted to the network. The operating system should handle efficiently the interrupt requests from the network controller so that the Tx buffers empty at a higher pace than filling, thus avoiding Tx overflow and the resulting loss of data A discussion on bounds, limita tions and operating system performance for handling IRQs from fast Ethernet and A TM devices can be found in [6,7].…”

“…The engineering of embedded Linux A TM for the MPC8260 family of communications processors is described in [2]. There we sketch the reference system and driver architecture and discuss items of the SAR mechanism and UTOPIA mode programming, while resolving important issues related to the Linux kernel, such as the packet forwarding performance and support of new devices in earlier kernels.…”

“…Details of the required A TM device driver interface elements across Linux kernels 2.4 and 2.6 are given in [4]. A pre-alpha release of the device driver including the UTOPIA interface and UBRlCBR services was released to the Linux community to appease the ever-increasing demand for the release of a Linux A TM driver for the MPC8260 [6]. The importance of this development to the embedded networking community is evident by the several thousands visits to the released driver web page and code downloads.…”
