Hamming codes are a class of binary linear codes. They can detect up to two simultaneous bit errors, and correct single-bit errors. In particular, a single-error-correcting and double error detecting variant commonly referred to SECDED.-a) Develop a Verilog module that will generate a 7-bit encoded data from a 4-bit data. Simulate your design for two inputs. Use even or odd parity according to the least significant figure of your ID number.
b) Develop a Veriog module for generating pseudorandom 4-bit data using Linear Feedback Shift Register( LFSR) method.
c) Develop a Verilog module to emulate one bit error in the data transmission. This can be done by changing only one of the encoded bits at each clock cycle. You may use a ring-counter and XOr gates for doing this. This arrangement will insert error in consecutive bits at each clock cycle.
d) Design a Hamming error detection and correction circuit to restore the original data.
e) Compare the original data with the restored data to verify the error correction capability of your design. If the two data sets are equal an OK signal will be set.
