How To Compile

cd Branchsim
javac Branchsim.java

Then run with 4 parameters:

java Branchsim [FILE_NAME] [M_HISTORY_BIT] [N_BIT_PREDICTOR] [BITS_TO_INDEX]

Examples:

java Branchsim gcc-8M.txt 6 1 12  // 6 history bits, 1-bit predictor, 12 bits to index
java Branchsim gcc-8M.txt 6 2 12

java Branchsim gcc-8M.txt 6 1 8
java Branchsim gcc-8M.txt 6 2 12

Notice that:

• FILE_NAME ∈ {gcc-8M.txt, gcc-10k.TXT}
• M_HISTORY_BIT ∈ [0, 12]
• N_BIT_PREDICTOR∈ [1, 2]
• BITS_TO_INDEX ∈ [4, 12]
