We begin with a computer implemented in a single-cycle implementation. When the stages are split by functionality, the stages do not require exactly the same amount of time. The original machine had a clock cycle time of 12 ns. After the stages were split, the measured times were IF, 3 ns; ID, 2.5 ns; EX, 2 ns; MEM, 3 ns; and WB, 1.5 ns. Use 0.1 ns for the pipeline register delay (i. e., the additional time to spend for keeping more registers and logic between pipeline stages). A. What is the clock cycle time of the 5-stage pipelined machine?
B. If there is a stall every 4 instructions, what is the CPI of the new ?machine?
C. What is the speedup of the pipelined machine over the single- cycle machine?
D. If the pipelined machine had an infinite number of stages, what would its speedup be over the single-cycle machine?

In a heat transfer course, we can derive the equation for the temperature distribution in a flat rectangular plate. in this example, we will look at a plate at steadystate with three sides being held at t1, and one side held at t2. the temperature for any location on the plate, t(x,y), can be calculated by where create a function (prob3_5) that will take inputs of vectors x and y in feet, scalar n, scalars l and w in feet and scalars t1 and t2 in degrees fahrenheit. it will output a matrix t which is the temperature of each x and y locations. t will have the number of columns equal to the number of elements in x and rows equal to the number of elements in y. though this can be done without loops (perhaps more efficiently), your program must use a nested loop.
