One popular FPGA interconnection network is based on the islandstyle model, where rows and columns of logic blocks are separated by channels containing routing wires. Switch blocks are placed at the intersections of the horizontal and vertical channels to allow the wires to be connected together. Previous switch block design has focused on the analysis of individual switch blocks or the use of ...

The paper describes design requirements of a basic stage (called MDAC Multiplying Digital-toAnalog Converter) of a pipelined ADC. There exist error sources such as finite DC gain of opamp, capacitor mismatch, thermal noise, etc., arising when the switched capacitor (SC) technique and CMOS technology are used. These non-idealities are explained and their influences on overall parameters of a pip...

This paper presents a new family of block codes referred to as Trellis Coded Block (TCB) codes, which are built using a trellis code and a linear block code (LBC). The TCB code (TCBC) construction is based on an algebraic structure inherent to many LBCs, which allows one to partition an LBC into sub-sets with a constant distance between every pair of code words in the subset. The proposed unifo...

In this paper we apply the cryptographic finite state machine approach as introduced in [1] to the design of symmetric key block ciphers.

We examine a generalization of the concept of Feistel networks, which we call Unbalanced Feistel Networks (UFNs). Like conventional Feistel networks, UFNs consist of a series of rounds in which one part of the block operates on the rest of the block. However, in a UFN the two parts need not be of equal size. Removing this limitation on Feistel networks has interesting implications for designing...

A brief paper-and-pencil instrument was developed to rapidly assess visuospatial ability and serve as an alterative to the WAIS Block Design subtests during screening or when assessment time is limited. The Design Organization Test (DOT) consists of square black-and-white grids with visual patterns similar to those of the Block Design subtests. Administration is straightforward and requires exa...

Neuroimaging studies began using block design and event-related design experiments. While providing many insights into brain functions, these fMRI design types ignore components of the BOLD signal that can teach us additional elements. The development of the mixed block/event-related fMRI design allowed for a fuller characterization of nonlinear and time-sensitive neuronal responses: for exampl...

The paper presents a new online tool that enables to build a Matlab/Simulink block scheme in the Internet environment. The block scheme can be designed in similar manner as it is offered by local installation of Matlab. The application was created by widely used technologies as XHTML, CSS, JavaScript, PHP together with AJAX approach. The created application can be used as a supporting tool in v...
