They are very much the same, except VHDL syntax is derived from Ada while Verilog syntax is derived from C. ==================================== moreover, VHDL is a system level language whereas verilog is a gate level (circuit level) language. Hence, verilog is easy to learn than VHDL.
Its a scam it happened me twice.First you download the movie n it says buy the XVOD Decoder It is strongly recommended not to buy the decoder its simply a scam
To upgrade your Strong 4669x decoder, first ensure that you have the latest firmware available from the manufacturer's website. Download the firmware onto a USB drive and connect it to the decoder. Access the settings menu on the decoder, navigate to the firmware upgrade section, and follow the prompts to install the update. After the upgrade, restart the decoder to complete the process and ensure optimal performance.

8/3 is a fraction.
You need 9 3-to-8 decoders. 8 decoders for selecting one of 64 lines. 1 decoder for enabling 1 decoder out of 8 decoder.
karthika only know answer to this question
8:256 decoder circuit can be implemented by using 4:16 decoder circuit
Use two 2-4 decoders.
chuma da do chuma da do!
The 74138 is a 3 to 8 decoder. When enabled, one of the 8 outputs is low, based on the binary value of the 3 inputs.
VHDL is a hardware description language. You can describe the hardware in three different ways using VHDL. 1. dataflow model 2. behavioral model 3. structural model
A virtual calculator can be implemented using VHDL. We call it VHDL calculator.
Vhdl has got three models - programming styles. 1. data flow model 2. behavioral model 3. structural model.
A full adder can be implemented using a decoder by utilizing a 3-to-8 line decoder to decode the three input bits: A, B, and Carry-in (Cin). The decoder generates eight output lines corresponding to all possible combinations of the three inputs. The outputs of the decoder can then be combined with logic gates to derive the Sum and Carry-out outputs of the full adder. Specifically, the Sum output can be generated by ORing the appropriate outputs of the decoder, and the Carry-out can be derived from a combination of specific outputs as well.
An N-2N decoder is a digital circuit that converts N input lines into 2^N output lines. For each unique combination of the input lines, one specific output line is activated while all others remain inactive. For instance, if there are 3 input lines (N=3), the decoder will produce 2^3 = 8 output lines, allowing it to represent all combinations of the 3 inputs. This type of decoder is commonly used in memory address decoding and data routing applications.
Decoder is a circuit which have n inputs and 2^n outputs.I think you want to say encoder which have 2^n input and n output lines. So your required chip is 8(2^3)X3 encoder which does not exist.
