The base CPI of a system, excluding both memory and cache accesses, is C. Loads and stores collectively constitute LS% of all instructions Accessing the L1 data cache takes LD cycles (accounted for in base CPI). Accessing the L1 instruction cache takes LI cycles (accounted for in base CPI). Misses to main memory take an average of D cycles. The L1 D-cache miss rate/access is MD. The L1 I-cache miss rate/access is MI. Our research team tries to provide the solution to increase different characteristics of the system. First, suppose we want to improve the AMAT for our system by placing an L2 Cache with 4*LD access time. How high can be the miss rate so we can still improve the AMAT?

answer; ///i believe that the correct answer is (copper);

we can all learn from our past mistakes because we all have different ways of learning different types of techniques. my way may or may not another classmate remember and have the repetition to acknowledge such standard. such as remembering acronyms. using abbreviations to us remember keep things in order in our memory. this us figure out what comes next in the sequence. if so, what we have is a sentence of just letters all in caps. we either know the meaning or have no idea what it stands for. most of the time we know the meaning and context. but most of us who don't know, should learn by having a quick glance at what needs to be remembered. such as repetition in the memory for acronyms. one way that me, is the fact that i'm always doing math and english assignments. so we have to remember specific meanings such as soapstone for documents, such as citing correctly. or pemdas for doing the equations correctly, even if it's the super long way. this works for everyone. you just have to find what works for you by practicing and repetition daily.
