4.15 The importance of having a good branch predictor depends on how oftenconditional branches are executed. Together with branch predictor accuracy, thiswill determine how much time is spent stalling due to mispredicted branches. Inthis exercise, assume that the breakdown of dynamic instructions into variousinstruction categories is as follows:R-TypeBEQJMPLWSW40%25%5%25%5%Also, assume the following branch predictor accuracies:Always-TakenAlways-Not-Taken2-Bit45%55%85%4.15.1 [10] <$4.8> Stall cycles due to mispredicted branches increase theCPI. What is the extra CPI due to mispredicted branches with the always-takenpredictor? Assume that branch outcomes are determined in the EX stage, that thereare no data hazards, and that no delay slots are used.

Calculating Extra CPI: From the above information, the first three execution cycles are IF, ID, EX.…

(Practice) Although the total number of bytes varies from computer to computer, memory sizes of millions and billions of bytes are common. In computer language, the letter M representsthe number 1,048,576, which is 2 raised to the 20th power, and G represents 1,073,741,824, which is 2 raised to the 30th power. Therefore, a memory size of 4 MB is really 4 times 1,048,576 (4,194,304 bytes), and a memory size of 2 GB is really 2 times 1,073,741,824 (2,147,483,648 bytes). Using this information, calculate the actual number of bytes in the following: a. A memory containing 512 MB b. A memory consisting of 512 MB words, where each word consists of 2 bytes c. A memory consisting of 512 MB words, where each word consists of 4 bytes d. A thumb drive that specifies 2 GB e. A disk that specifies 4 GB f. A disk that specifies 8 GB

4.19.16: [5] <COD §4.6>. In this exercise, we examine how pipelining affects the clock cycle time of the processor. Problems in this exercise assume that individual stages of the datapath have the following latencies: Also, assume that instructions executed by the processor are broken down as follows: (a) What is the clock cycle time in a pipelined and non-pipelined processor? (b) What is the total latency of an lw instruction in a pipelined and non-pipelined processor? (c) If we can split one stage of the pipelined datapath into two new stages, each with half the latency of the original stage, which stage would you split and what is the new clock cycle time of the processor? (d) Assuming there are no stalls or hazards, what is the utilization of the data memory? (e) Assuming there are no stalls or hazards, what is the utilization of the write-register port of the "Registers" unit? No hand written and fast answer with explanation

In this case, there will be a structural hazard every time a program needs to fetch an instruction during the same cycle in which another instruction accesses data. 4.22.1 [5] <§4.5> Draw a pipeline diagram to show were the code above will stall. 4.22.2 [5] <§4.5> In general, is it possible to reduce the number of stalls/NOPs resulting from this structural hazard by reordering code? 4.22.3 [5] <§4.5> Must this structural hazard be handled in hardware?

The following problem illustrates the way memory aliasing cancause unexpected program behavior. Consider the followingprocedure to swap two values:1 /* Swap value x at xp with value y at yp */2 void swap(long *xp, long *yp)3 {4 *xp = *xp + *yp; /* x+y */5 *yp = *xp - *yp; /* x+y-y = x */6 *xp = *xp - *yp; /* x+y-x = y */7 }If this procedure is called with xp equal to yp , what effect will ithave?A second optimization blocker is due to function calls. As an example,consider the following two procedures:1 long f();23 long func1() {4 return f ()+ f ()+ f ()+ f () ;5 }67 long func2() {8 return 4*f();9 }It might seem at first that both compute the same result, but withfunc2 calling f only once, whereas func1 calls it four times. It istempting to generate code in the style of func2 when given func1 asthe source.Consider, however, the following code for f:1 long counter = 0;23 long f() {4 return counter++;5 }This function has a side effect—it modifies some part of the globalprogram state.…
Considering the following contents of Stack Segment (SS) Register and Stack Pointer (SP) Register: SS = A5B0H, SP = 4DF0H (a) Calculate the values of Top of Stack (ToS) and Bottom of Stack (BoS)? (b) Consider the following operations on the stack: PUSH AX PUSH [CX] PUSH 10 POP [BX] POP AX What is the value of ToS after all these operations? Also, provide the value of ToS after each instruction.
In the working set model, the idea is to examine the most recent delta page referances. It is also known as an approximation of the Program's Locality. If the total demand is greater than the total number of available frames (D>m) then it will cause thrashing, because in this case, some processes will not have enough frames. Below you see 3 processes and their excepted memory references during their execution. When will the thrashing happen to occur according to the working set model? Assume total memory(m) is 10 and Delta is 5
In this exercise, we examine how data dependences affect execution in the basic 5-stage pipeline described in Section 4.5. Problems in this exercise refer to the following sequence of instructions: or $t0, $s2, $t0 and $t0, $a0, $s3 lw $t5, 24($t0) sw $t0, 12($s6) sub $t3, $t0, $t5 Also, assuming the following cycle times for each of the options related to forwarding: Without Forwarding With Full Forwarding With ALU-ALU Forwarding Only 220 ps 260 ps 250 ps Assume there is no forwarding in this pipelined processor. Indicate hazards and add nop instructions to eliminate them.
