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?

Show that there is a language a ⚆{0, 1} â— with the following properties: 1. for all x â a, |x| ≤ 5. 2. no dfa with fewer than 9 states recognizes a. hint: you don’t have to define a explicitly; just show that it has to exist. count the number of languages satisfying (1) and the number of dfas satisfying (2), and argue that there aren’t enough dfas to recognize all those languages. to count the number of languages satisfying (1), think about writing down all the strings of length at most 5, and then to define such a language, you have to make a binary decision for each string about whether to include it in the language or not. how many ways are there to make these choices? to count the number of dfas satisfying (2), consider that a dfa behaves identically even if you rename all the states, so you can assume without loss of generality that any dfa with k states has the state set {q1, q2, . . , qk}. now think about how to count how many ways there are to choose the other four parts of the dfa.

Write a program that inserts the digits of an integer into an array in originalorderfollowed by reverse order. first, promptthe user to enter a positive integer(> 0). determine the number of digits of the integer. create a dynamically allocated integer arrayof a size twice the number of digits.now insert the digits in original order which will occupy half of the array. then, insert the digits in reverse order.finally, output thedigits in thearray.use at least two functions to organize your program.
