Predictors Given the following piece of code below, compute the accuracies of the 1 bit and...
You are given the following code in C, a (2,1) global history predictor (hint: here we need four columns that each holds predictors of size 1 bit, and a number of rows…) and a 2-bit predictor (i.e., (0,2) predictor) for (i=100; i>0; i—-) { // Branch1 if (i mod 2 ==0) { //Branch2 ……… } else { ……. } } Q 1: Which predictor is the most suitable for Branch1 and why? Q 2: Which predictor is the most suitable...
(25 points) Consider a 1-bit and a 2-bit predictor. In the table below, indicate the prediction for the branch and whether the prediction is correct. For the 1-bit predictor use the notation"1 for taken, and "0 for not taken states. For the 2- bit predictor, use "11 for strongly taken state, "10 for weakly-taken state.'00 for strongly-not-taken state, and "01" for weakly-not-taken state. Assuming the first entry in the table, fill in the predictor's state after branch resolution for each...
Given this piece of code fragment: (10%) for (int x = 0; x < 10; x++) if ( x % 4 >= 2) cout << "OK" << endl; Assuming the branch prediction by default is “TAKEN”, What is the accuracy of branch prediction of the if statement when we use a 1-bit branch history? What is the accuracy of branch prediction of the if statement when we use a 2-bit branch history?
Problem 1 Consider the piece of ARM Cortex MO+ assembly code given below and answer the following questions: mw 1.AGAIN CMP RO, #10 BLE LESSEQUAL MOVS RO, #0 B DONE LESSEQUAL ADDS RO, RO, R1 B AGAIN 5. DONE 1. Assume RO is initialized with the value 20, what is the value of RO when the code above completes execution? How many times is Instruction 5 executed? Assume RO is initialized with the value o, and R1 with the value...
1. Suppose we have a 5-stage pipeline CPU and run the following instructions: or $tl, $t2, $t3 or $t2, $tl, $t4 or $tl, $tl, $t2 1.1. What dependencies are there in the code? 1.2. Suppose there is no forwarding. What hazard may happen? Draw the pipeline diagram and insert stall (nop) to prevent these hazard. 1.3. If the pipeline has full forwarding. Are there still hazard? If so, draw the pipeline diagram and insert stall (nop) to prevent the hazard....
Hello, I have my piece of C programming code and I have a pointer initialized to point to my array and I need help to display the contents of my array using a while loop or do-while loop. The stop condition should be when the pointer reaches '\0'. The code is below: #include <stdio.h> int main () { char array[80]; printf("Enter a string: "); scanf("%[^\n]", &array); printf("%s\n", array); char * p; p = array; }
For the following code, answer the questions below. { for (i=0; i < 6; i++) { do something} } In predicting the branch terminating the inner loop (located at the end of the loop), answer the prediction success rate with the following schemes. Assume 0 for NOT-TAKEN and 1 for TAKEN. Question)) A prediction table of two-bit saturating counters (initial value = 00) indexed by PC
Q4) what is the output after the code below is executed? #include <stdio.h> #1 nclude<string.h> int main) char abc[100]-"Good Luck in Your Programming Final" int i, ; while(abc[i]!= '\0'){ if(abc[i]' if(abc[i+1]-'&&abci+1] -'0' else printf"c", abcli-1]) printf("\n w = %d return 0; \n", w); Place you answer here 4 l Page
Write an Verilog code for a 8-bit subtractor (Bits are in 1's complement) using the following: 1. 5-bit parallel adder 2. 3-bit parallel adder The condition are as follows: 1. The Most Significant bits of the subtractor must be given to the 5-bit parallel adder. 2, The Least Significant bits of the subtractor must be given to the 3-bit parallel adder. 3. The input A will be assign to the switches with the least significant bit A[0] linked to SW0....
