Three-input Majority Voter
-- The entity declaration is followed by three alternative architectures which achieve the same functionality in different ways.
Swfdec still is development software, but has also followed a rigid
no-crashes-allowed policy. I believe it s stable enough now to be
installed as a default plugin for people that can live with occasional
crashes of their browser. But don t blame me if it does crash. File a

In this paper, we discuss efficient coding and design styles using verilog. This can beimmensely helpful for any digital designer initiating designs. Here, we address different problems rangingfrom RTL-Gate Level simulation mismatch to race conditions in writing behavioral models. All theseproblems are accompanied by an example to have a better idea, and these can be taken care off if thesecoding guidelines are followed. Discussion of all the techniques is beyond the scope of this paper, however,here we try to cover a few of them.
A number of conventional solutions have been available forthe design of a DC/DC converter where the output voltageis within the input voltage range—a common scenarioin Li-Ion battery-powered applications—but none werevery attractive until now. Conventional topologies, suchas SEPIC or boost followed by buck, have numerousdisadvantages, including low effi ciency, complex magnetics,polarity inversion and/or circuit complexity/cost. TheLTC®3785 buck-boost controller yields a simple, effi cient,low parts-count, single-converter solution that is easyto implement, thus avoiding the drawbacks associatedwith traditional solutions.
Express Mode uses an 8-bit wide bus path for fast configuration of Xilinx FPGAs. Thisapplication note provides information on how to perform Express configuration specifically forthe Spartan™-XL family. The Express mode signals and their associated timing are defined.The steps of Express configuration are described in detail, followed by detailed instructions thatshow how to implement the configuration circui

1 Communication Protocol (Computer as master)
The communication protocol describes here allows your computer to access 4096 internal registers (W0000-W4095) and 1024 internal relays (B0000-B1023) in the Workstation..
1.1 Request Message Format
Request message is a command message to be sent from the computer to the Workstation. The data structure of request message is shown below. Note that numbers are always in hexadecimal form and converted into ASCII characters. For example, Workstation unit number 14 will appear in the message as character 0(30h) followed by character E(45h); a BCC of 5Ah will appear in the message as character 5(35h) followed by character A(41h).
