Question
What does the following Verilog code represent?
module unknown(
input a,
input b,
input c,
input d,
input [1:0] s,
output reg y
);
always @(a,b,c,d,s)
case (s)
2'b00: y=a;
2'b01: y=b;
2'b10: y=c;
2'b11: y=d;
default: y=a;
endcase
endmodule
Please choose from one of the following:
1. a decoder
2. a priority encoder
3. a 4x1 multiplexor
4. a not gate
Please choose from one of the following:
1. a decoder
2. a priority encoder
3. a 4x1 multiplexor
4. a not gate
Explanation / Answer
Please note that above Verilog code is for Priority Encoder as A priority encoder mean giving priority to a one bit if two or more bits meet the criteria. Sharing one more example of same as below :
Verilog code for a 3-bit 1-of-9 Priority Encoder.
