[30 pts] Problem 1
[30pts] Problem3: Encoder Decoder, Memory and State machine
Using Hamming code described in class, design an error correction code (ECC) for a 8-bit data word.
– Required number of check bits is log2N+1, where N is data word length
– ECC bits whose indices are powers of two are used as check bits.
– If we write the indices of ECC bits in binary, the check bit with a 1 in position i of its index is the XOR of data ECC bits that have a one in position i of their indices.
[3 pts] What is the length of total code word? Which bits are check bits and which one are data bits?
[7 pts] Write down the equations and computation of the ECC bits for 8-bit data 01111111 and write the complete Encoded code word. This needs to show your work.
Now You need to design a complete Verilog for this Encoder Decoder, Memory and State machine shown below. Memory module has 128x8bit data prestored. Upon start signal and Enc=1 Encoder reads inputs from memory, performs encoding and sends out the Encoded output to store in the output SSRAM. When all 128 data are encoded. When Enc=0, the data from the output SSRAM is read by Decoder module and finds out if there is an error (Error=1 or 0), the Error Location, Decoded Out (the corrected data).
[2 pt] What is the size of both SSRAMs? Address bit, data bits and total size.
[5 pt] Draw a detailed block diagram of the module with inputs to each block, required signals and their connections. Explain how your module works.
[5 pts] Write verilog for writing and reading from your two memories (based on the signals that you defined).
[12 pt] Design a state machine that computes the function
[6 pts] Write Verilog for the datapath and complete module.
