Practice Problem 7.3 (solution page 718)
Let a and b denote object modules or static libraries in the current directory, and let a→b denote that a depends on b, in the sense that b defines a symbol that is referenced by a. For each of the following scenarios, show the minimal command line (i.e., one with the least number of object file and library arguments) that will allow the static linker to resolve all symbol references.

What if the request came from C instead of D?arrow_forwardPlease provide solution for the following:arrow_forward4.22 [5] <§4.5> Consider the fragment of LEGv8 assembly below: STUR X16, [X6, #12] LDUR X16, [X6, #8] SUB X7, X5, X4 CBZ X7, Label ADD X5, X1, X4 SUB X5, X15, X4 Suppose we modify the pipeline so that it has only one memory (that handles both instructions and data). 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? We have seen that data hazards can be eliminated by adding NOPs to the code. Can you do the same with this structural hazard? If so, explain how. If not, explain why not. 4.22.4 [5] <§4.5> Approximately how many stalls would you expect this…arrow_forward
- 3. The diagram below shows the main land routes for vehicular traffic between points A and G in a city. The figures in the arcs represent the cost of traveling between each pair of nodes. a) Manually apply Dijkstra's algorithm to find the cheapest route between A and G (visited nodes and total distance). b) Formulate a linear programming problem in extended form, to determine the shortest route to travel from A to G. Do not use subscripts, name 14 variables, for example XFE would be the variable that indicates that the arc from F to E is used. c) If there is a fixed cost for visiting each node, modify the formulation of the problem to include said fixed cost in the objective function, and the variables and restrictions that are required.

The ISP needs to distribute these addresses to three groups of customers as follows: a. The first group has 64 customers; each needs 256 addresses. b. The second group has 128 customers; each needs 128 addresses. c. The third group has 128 customers; each needs 64 addresses. Design and Implement the sub blocks and find out how many addresses are still available after these allocations.arrow_forward1. Develop a system of linear equations for the network by writing an equation for each router (A, B, C, D, and E). Make sure to write your final answer as Ax=b where A is the 5x5 coefficient matrix, x is the 5x1 vector of unknowns, and b is a 5x1 vector of constants. 2. construct the augmented matrix [A b] and then perform row reduction using the rref() function. Write out your reduced matrix and identify the free and basic variables of the system. 3. Use MATLAB to compute the LU decomposition of A, i.e., find A = LU. For this decomposition, find the transformed set of equations Ly = b, where y = Ux. Solve the system of equations Ly = b for the unknown vector y. 4. Compute the inverse of U using the inv() function. 5. Compute the solution to the original system of equations by transforming y into x, i.e., compute x = inv(U)y 6. Check your answer for x1 using Cramer’s Rule. Use MATLAB to compute the required determinants using the det() function.arrow_forward

- 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 explanationarrow_forward10.
