- Step 1 of 6To compute the effective CPI of IMPS, the CPI formula will beapplied after performing the following operations:• First calculate the average instruction frequencies of the gapand gcc.• Divide the major instructions in four categories. Thesecategories also contain two subcategories for conditionalbranches.Here, round to even scheme is applied to find the averageof gap and gcc. It is because the sum of gap is 100.2 and the sumof gcc is 99.5. It is due to rounding error, because each totalmust consists 100. Therefore, to remove this error the schemeround to even be applied. In this scheme, the leastsignificant digit will always be made even.
- Step 2 of 6The four main categories are given below:ALU: In this the operands are taken from the set ofregisters and also that set of registers are returned asresult.The instructions add, mul, compare, sub, load imm, cond move,shift, or, xor, and, other logical are categorized under ALUinstruction’s frequency.The following table shows the average instruction frequencies ofgap and gcc for ALU instruction’s category.InstructionAverage of gap and gcc percentageXOR2.0shift2.4mul0.8OR8.2load imm3.6cond move0.5and4.4sub2.0compare4.4add20.0other logical0.2• The ALU instruction’s frequency will be calculated by addingthe frequencies of add, mul, compare, sub, load imm, cond move,shift, or, xor, and, other logical.• Hence, the total ALU instruction’s frequency will be.
- Step 3 of 6Load/store: It is used to access memories.The instructions load and store are categorized under load/storeinstruction’s frequency.The following table shows the average instruction frequencies ofgap and gcc for load/store instructions.InstructionAverage of gap and gcc percentagestore11.8load25.8• The load/store instruction’s frequency will be calculated byadding the frequencies of load and store.• Hence, the total load/store instruction’s frequency willbe.
- Step 4 of 6Conditional branches: Depending upon the differentcondition, a new value is given to the program counter.The following table shows the average instruction frequencies ofgap and gcc for load/store instructions.InstructionAverage of gap and gcc percentagecond branch10.7• The conditional branches instruction’s frequency will becalculated by taking the frequencies of load cond branch• The conditional instruction’s frequency will be
- Step 5 of 6Jumps: A new value is set to the program counter nomatter what.The following table shows the average instruction frequencies ofgap and gcc for jump instructions.InstructionAverage of gap and gcc percentagereturn1.1call1.1jump0.8• The jump instruction’s frequency will be calculated by addingthe instructions jump, return and call.• Hence, the total jump instruction’s frequency will be.Hence, the effective CPI will be calculated as:
- Step 6 of 6Hence, the effective CPI for MIPS using figure A.27 is.
- ALU instruction frequency = 45.8% or 0.458 also, the load/store instruction frequency = is 37.6% or 0.376 which was not shown correctly during the calculations (0.367 x 1.4) another typo, other than that I really appreciate the work.
