(B+C) × (D+E) F 1. Write code to implement the expression: A = on 3-, 2-, 1- and 0-address machines. In accordance with programming language practice, computing the expression should not change the values of its operands. 2. Solve the following: a) In a computer instruction format, the instruction length is 11 bits and the size of an address field is 4 bits. Is it possible to have: 5 2-address instructions, 45 1-address instructions and 32 0-address instructions using the spec- ified format? Justify your answer. 3. Suppose a computer using direct mapped cache has 232 bytes of byte-addressable main memory and a cache size of 512 bytes, and each cache block contains 128 bytes. a) How many blocks of main memory are there? b) What is the format of a memory address as seen by cache, i.e., what are the sizes of the tag, block, and offset fields? c) To which cache block will the memory address 0x13A4498A map?

(Access to array elements should be done according to offset-address increment notation.)Sample Run:Biggest : 23Smallest : 0Sample Main................................/*prototip*/int main(){int array[5]={23, 4, 2, 0, 8};int biggest;int smallest;bigSmallFind(.............................)printf("Biggest : %d \n", biggest);printf("Smallest : %d \n", smallest);return 0; }
PART 1: ONE-DIMENSIONAL ARRAY Instruction: There are two lists of numbers. Create a resultant list whose elements are the product of the elements of the two lists. Example: List A 21 List B List C 630 500 30 50 10 Write a Java program using a one-dimensional array that accepts as input an integer value asking for the number of elements for each list. This will be used to generate random numbers (5 to 69) for the one-dimensional arrays (List A and List B). The program will compute for the product and store it in another array (List C). Display the result similar to the Example above. Sample Input/Output: Depicted below are sample outputs when the program is executed (the items in bold characters are input from the user, while the items in bold italic are generated, calculated and printed by the program): Input the number of elements: 3 List A List B List C 630 500 250 21 30 50 10 25 10 Input the number of elements: 5 List A List B List C 31 13 403 21 30 630 500 50 10 60 41 2460 25 10…
