VHDL implementation of the twofish cipher for 128,192 and 256 bit keys. The implementation is in library-like form All needed components up to, including the round/key schedule circuits are implemented, giving the flexibility to be combined in different architectures (iterative, rolled out/pipelined etc). Manual in English is included with more details about how to use the components and/or how to optimize some of them. All testbenches are provided (tables, variable key/text, ECB/CBC monte carlo) for 128, 192 and 256 bit key sizes, along with their respective vector files.

The Hilbert Transform is an important component in communication systems, e.g. for single sideband modulation/demodulation, amplitude and phase detection, etc. It can be formulated as filtering operation which makes it possible to approximate the Hilbert Transform with a digital filter. Due to the non-causal and infinite impulse response of that filter, it is not that easy to get a good approximation with low hardware resource usage. Therefore, different filters with different complexities have been implemented. The detailed discussion can be found in "Digital Hilbert Transformers or FPGA-based Phase-Locked Loops" (http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=4629940). The design is fully pipelined for maximum throughput.

This control is another extension to the now standard and widely used ListView control. I have included some of the more common features: shaded columns, column sorting (with data type), but the real addition is the FILTERBAR features of the header. This implementation eliminates all of the work of dealing with the filter messages and item filtering by incorporating it into the control. This could have been implemented as delegates, but we create controls to do the work for us, don t we? I would like to thank Carlos H. Perez since a lot of the implementation came from examples he set with his ListViewEx control.

Cisco E-DI supports perl scripting through the CLI. This feature automates many of the server and network administration tasks. This section explains how to enable and disable the perl scripting service, and how to use Cisco E-DI Perl API for daily tasks. When a perl script is implemented by an administrator or a user, the script automatically inherits the user s security privileges and the user s operational context (either server or network). Each invocation of a

In this work an implementation of a geometric nonlinear controller for chaos synchronization in a Field Programmable Gate Array (FPGA) is presented. The Lorenz chaotic system is used to show the implementation of chaos synchronization via nonlinear controller implemented in a Xilinx FPGA Virtex-II 2v2000ft896-4. The main idea is to design a nonlinear geometric controller which synchronizes a slave Lorenz system to a master system and then implement them into the FPGA.

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.
