Hi all, I am trying to build a sequence detector to detect a decimal number like 10= 92 when a stream of numbers from 0-9 is given as input. Do you think just c= hanging the width of input i.e parallel inputs instead of series would resu= lt in pattern detection? I am lost in this, please help. If you have any re= sources around this do share them.

Hello everyone, I have recently started working on a project using Ethernet in an FPGA and I am using the UDP protocol for communication between the PC and the FPGA. The communication is happening point to point so I was wondering do I need ARP implementation in my stack or can I just broadcast the message. I am building a UDP stack but was wondering is ARP a necessary requirement. Also, the ...

Hi, In the working process for my private project, I use free Notepad++ to code VHDL code and appreciate it very much! Here is an example of how powerful Notepad++ is: In 27 files, I easily found that I use the statement "when others => null; " 119 times and the statement "end case;" 117 times. There are certainly 2 mismatches for the 2 types of statements. I found only 1 mismat

CS302 – Digital Logic Design Graded Discussion Board You are required to program a PAL device to design a 64-bit counter. The stated PAL can be programmed using ABEL (Advanced Boolean Expression Language) and VHDL (Verilog Hardware Descriptive Language). Which programming technology would you use to accomplish the task outlined considering the constraints given below?

Have anyone studied Pan's Algorithm previously ? http://people.eecs.berkeley.edu/~alanmi/publications/2005/iwls05_smr.pdf#page=3...

Have anyone studied Pan's Algorithm previously ? http://people.eecs.berkeley.edu/~alanmi/publications/2005/iwls05_smr.pdf#page=3 https://i.imgur.com/GO8s4BU.png 1. How is Pan's algorithm being a shortest-path algorithm when clock period is computed across the critical path (longest path) ? 2. Any idea about the modified version of Pan's algorithm described in Figure 2 on page ...

Most sorting algorithms I've noticed seem to have an interface somewhat like this: void someAlgorithm ( elemType[] elements); So to implement this algorithm an application needs to fill the {elements} array, call the {someAlgorithm()} algorithm, and then read out the (sorted) elements of {elements}. For an {elements} object that contains n {elemType}s, how long does it take to fi

Hi, I have a problem that does not do what is expected. I have several modules linked together from top to bottom. Each module has 3 error output signals: Error_O, Error_Level_O, and Error_Code_O. If a module has an error, Error_O = '1', Error_Level_O and Error_Code_O have their proper error info. There are 3 arrays to correct that information from each of those modules: Error_O_m(), Error_...
