[Industry research] Introduction_to_DUAL-CORE.doc.tar DL : 0: Introduction to Dual-Core Development This procedure will introduce tools that are useful for developing applications that can utilize both processing cores available with the OMAP 5912 processor. Introduced are the LinuxDSP tools for compiling DSP source code and DSP Gateway which allows the DSP processor to be controlled through Linux running on the ARM core. To use DSP Gateway, the Linux kernel is updated to version 2.6.12 and the necessary patches are applied to configure the kernel for the OMAP 5912.-Introduction to Dual-Core Development This procedure will introduce tools that are useful for developing applications that can utilize both processing cores available with the OMAP 5912 processor.

[Industry research] Comparing-the-real-time-scheduling-policies-of-th DL : 0: By Le Trung Thang,April 2012 By default, the Linux kernel build used in the many open source distributions is the normal/default kernel which doesn’t support real time scheduling. If an embedded developer wants to compare the scheduling policies of Linux to a real time operating system it is more useful to compare RTOS performance to a version of Linux that does have real-time features. Fortunately, in addition to this default kernel, there is also available a Real-time kernel version that supports a real-time scheduling policy. In this article and in the code examples that are included, an effort is made to compare the real time operations of standard and real-time Linux with normal RTOS operation and evaluate the differences and similarities.

[Industry research] A-Tale-of-Four-Kernels-(FreeBSD--Linux--OpenSolar DL : 0: By Diomidis Spinellis,Athens University of Economics and Business, Greece, May 2008 The FreeBSD,GNU/Linux,Solaris,and Windows operating systems have kernels that provide comparable facilities. Interestingly, their code bases share almost no common parts, while their development processes vary dramatically. We analyze the source code of the four systems by collecting metrics in the areas of file organization, code structure, code style, the use of the C preprocessor, and data organization. The aggregate results indicate that across various areas and many different metrics, four systems developed using wildly different processes score comparably. This allows us to posit that the structure and internal quality attributes of a working, non-trivial software artifact will represent first and foremost the engineering requirements of its construction, with the influence of process being marginal, if any.
