A quicksort algorithm sourcecode that together with the sourcecode for equalTo, sorts a integer array from lowest to highest and then checks if two numbers in the array added with eachother equals another integer.
This chapter enables the reader to:
• Know the content and organization of this book, and how to use it to analyze
and model radar system performance
• Understand the concept of radar operation, the functions performed by radar,
and how radar may be used in various applications
• Understand the characteristics of functional radar models and how they are
used to analyze overall radar performance.
Learn how to leverage a key Java technology used to access
relational data from Java programs, in an Oracle environment.
Author Donald Bales begins by teaching you the mysteries of
establishing database connections, and how to issue SQL queries
and get results back. You ll move on to advanced topics such as
streaming large objects, calling PL/procedures, and working
with Oracle9i s object-oriented features, then finish with a look at
transactions, concurrency management, and performance
This paper describes a bus mastering implementation of the PCI Express protocol using a Xilinx FPGA. While the theoretical peak performance of PCI Express is quite high, attaining that performance is a complex endeavor on top of an already complex protocol. The implementation is described and its performance is analyzed. Source code is offered for free download via the web.
This is a simulator written in Tcl to simulate a network node carrying GSM and GPRS traffics with QoS mechanisms. The payload type including circuit-switched voice, VoIP and web traffic, and the performance including packet drop, delay can be analyzed. The implemented QoS mechanism is DiffServ, with 4 RED queues for different services with different priorities.
The software and hardware development fields evolved along separate paths through the end of the 20th century. We seem to have come full circle, however. The previously rigid hardware on which our programs run is softening in many ways. Embedded systems are largely responsible for this softening. These hidden computing systems drive the electronic products around us, including consumer products like digital cameras and personal digital assistants, office automation equipment like copy machines and printers, medical devices like heart monitors and ventilators, and automotive electronics like cruise controls and antilock brakes.
Embedded systems force designers to work under incredibly tight time-tomarket, power consumption, size, performance, flexibility, and cost constraints.
Many technologies introduced over the past two decades have sought to help satisfy these constraints. To understand these technologies, it is important to first distinguish the underlying embedded systems elements.
While faster processors, larger memory, and powerful graphics are fundamental requirements for workstations, users
are also demanding a low-cost, solution-based approach wrapped around a standards-based technology. The Sun UltraTM
20 Workstation, which leverages the AMD OpteronTM processor with Direct Connect Architecture based on AMD64
technology, provides multiple operating system choices and leading nVidia graphics, delivers a platform that offers
flexibility and performance in a cost-effective package with solutions to benefit customers across the board.
