MIPS Help asap!

Consider a processor implementation, P1 of some RISC (MIPS or risc-v) instruction set architecture (ISA). There are three classes of instructions (ALU, Ld/St, and Branch) in the instruction set. P1 has a clock rate of 6.0GHz ! The average number of cycles for each instruction class and their frequencies (for a typical program mix) are as follows: Instruction Class P1 CPI Frequency Ld/St?1/3 ALU 1 1/3 structure.com/couree6/21887/qulzze6/242601 midtem: F22 CS tOLO COMPUIEK ARC.HITECORGANIZNILN O1Y, 02 W Riordan 20511, 21871 Branch 21/3 (a) What is the Ld/StCPI required for P1 to achieve an average CPI of 2.0 (rounded to the nearest integer)? (b) What is the mips rating for P1 (rounded to the nearest integer)? (c) If the average Google search takes 30 billion instructions to execute, how long in seconds would P1 as specified above need to do that search (rounded to the nearest integer)? (d) Which one of the Eight Great Ideas could be utilized to dramatically (more than a factor of 10 ) decrease the search time? (e) Which one (most important) of the remaining Great Ideas enabled that Great Idea (your previous answer)
