That can lead to either increasing the clock speed or decreasing the power consumption Multiprocessing can be also used to increase speed or reduce power brPage 2br YORK UNIVERSITY CSE4210 Pipelining ab yn xn2 xn1 xn tion multiplica one and additi Parallel programming 5 - 2 arallel Version 1. Our first parallel version simply splits the outer loop: id := process_fork (p); for (i=id; in ; i=i+p) { y [i] = 0; for (j=0; jn Chapter. 4. Repeated Tasks are for Computers. Think back to any very difficult quantitative problem that you had to solve in some science class. How long did it take?. How many times did you solve it?. 2 w1w2w3w4w1w2w3w4g1 (high byte)g2 (low byte)FFFFg5 (high byte)g6 (low byte)G (1 to 32)ABAB Figure 1. Skipjack cryptographic algorithm The application of the technique is demonstrated using the simp Iteration. We’ve seen many places where repetition is necessary in a problem.. We’ve been using the for loop for that purpose. For loops are called . definite. loops because we know how many times the loop needs to be executed. CS303E: Elements of Computers and Programming. Nested Loops. Nested loops. occur when a loop has one or more other loops in its body. Outside loop variable is constant while the inside loop executes to completion. if. Lesson.

The general principle of nesting loops is that the inner loop must completely finish its execution before the next iteration of the outer loop starts. Shamsa. Hassan . Alhassouni. For -G7. .
