Assume a single standard three stage (load, execute, write back) functional unit. Also assume that the execution (stage 2) of multiplication requires 3 units of time, subtraction requires 2 units of time, and addition requires 1 unit of time. Stages 1 and 3 require 1 unit of time. If the computer can perform instruction level parallelism, then how many units of time are there when an instruction is stalled in stage 1? A stall is when an instruction has ENTERED and COMPLETED stage 1, but is not able to leave stage 1 because stage 2 is occupied. Do NOT count the 1 unit of time that an instruction spends in stage 1 while the operands are loaded.
type function2(type a, type b, type c, type d){
type var1 = a - b;
type var2 = var1 * c;
type var3 = a + d;
return var3;
}

You need to design a circuit that implements the functions in the following table: s0 s1 function0 0 a + 10 1 a – b1 0 a + b1 1 a – 1s0 and s1 are 1-bit control inputs to select the function of the circuit. inputs a and b are 4-bitnumbers in 2s complement form. the output is also a 4-bit number in 2s complement form.you are allowed to use only one ttl 7483 4-bit adder to implement all the functions. but anynumber of other components (except the adder) can be used.hint: design a combinational logic circuit to modify the input b and the “carry input” of theadder depending on the control inputs s0 and s1.important: lab grade will depend on the working of the circuit & will be checked of by your labinstructor.1. is the output valid for the following input combinations: a. s0 = 0, s1 = 0, a = 7, b = 3? b. s0 = 0, s1 = 1, a = 7, b = 3? c. s0 = 1, s1 = 0, a = -4, b = -5? d. s0 = 1, s1 = 1, a = -8, b = 6? 2. what is the range of inputs (for both a and b) that will produce the valid output for all the functions?

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.

Write an expression that will cause the following code to print "equal" if the value of sensorreading is "close enough" to targetvalue. otherwise, print "not equal". ex: if targetvalue is 0.3333 and sensorreading is (1.0/3.0), output is:
