Let's attempt to answer a fundamental question: 'How does the Computer execute a Program?' Let's describe this with the help of an example from higher level language domain.
Problem: Write a program to add two numbers.
A sample C program (Assuming two fixed values of numbers as a = 5 and b = 2)
1. #include < stdio.h >
2. main ()
3. {
4. int a =5, b=2, c;
5. c= a+b;
6. printf ("\n The added value is: % d", c);
7. }
Program at line 4 states variables which will be equal to 3 memory locations that are a, b and c. At line 5 these variables are added along with at line 6 value of c is printed.
However how will these instructions be executed by CPU? First you have to compile this program to convert it to machine language. Though how will the machine instructions look like? Let's suppose a hypothetical instruction set of machines of a size of 16 binary digits (bits) data and instructions. Each one of the instruction of machine comprises two components: (a) Operation code which specifies the operation which is to be performed by instruction and (b) Address of operand in memory on that given operation is to be performed.
Let's further presume that size of operation code is supposed to be of six bits consequently rest 10 bits are for address of operand. Also the memory word size is presumed to be of 16 bits. Figure below shows instruction and data formats for this machine. To simplify our discussion let's present operation code employing Mnemonics such as ADD, LOAD, STORE and signed decimal values for data and decimal values of operand addresses.
Q. Limitations of execution of instructions? 1. Size of memory shown in 16 words while instruction is capable of addressing 210 =1 K words of Memory. However why 210 since 10 b
Q. Using Library methods returns number of threads? #include void subdomain(float x[ ], int istart, int ipoints) { int i; for (i = 0; i x[istart+i] = 123.456;
Question 1: a) The aim of a computer network is to increase efficiency and reduce costs. Describe how networks achieve the above. b) Explain briefly how the bus topology op
Q. Example of processor arrangements? !HPF$ PROCESSORS P (10) This initiates a group of 10 abstract processors assigning them combined name P. !HPF$ PROCESSORS Q (4, 4)
What are the Difference between $display and $strobe Difference between $display and $strobe is that $strobe displays parameters at the very end of current simulation time unit
Your professor wants you to fill a two-dimensional N by N matrix with some numbers by following a specific pattern. According to his explanation as in the figure below, you have to
Why we need to construct state transition diagram Basically you need to construct a state transition diagram for each object with important behaviour. You need not construct on
Q. Sequential Execution of Instructions in RISC? Let's describe pipelining in RISC with an illustration program execution sample. Take the given program (R denotes register).
How to get the column count of a report? SY-LINSZ system variable gives the column count (line size) and SY-LINCT for line count.
Explain the concept of top-down design for a program. Top down Design: A top-down approach is fundamentally breaking down a system to gain insight into its compositional s
