Load the content of Memory location A into the Accumulator Register.

Perform the following conversion of numbers: 
i) Decimal (3456345123)10 to binary and hexadecimal
ii) Hexadecimal (CABFF114)h into Octal.

Add the content of memory location B to Accumulator Register

 Draw three more diagrams, each showing the state of the machine after execution of every instruction viz. LOAD, ADD and STOR. Show the changes in the values of Registers and memory locations, if any, due to the execution of the instruction. Show all the addresses and values in hexadecimal notations. 

Please refer to Figure 4 of Unit 1 of Block 1 on page 11 of the Instruction execution example.
Assuming a similar machine is to be used for the execution of the following three consecutive
instructions:

Draw a diagram showing the Initial State of the machine with the addresses and content of memory locations in hexadecimal. Show only those address locations of the memory that store the instruction and data. Also, show the content of all the stated registers. 

 Stores the content of the Accumulator register to memory location C. However, this machine is different from the example of Figure 4 in the following ways:
 Each memory word of this new machine is of 32 bits in length.
 Each instruction is of length 32 bits with 8 bits for operation code (opcode) and 24 bits for specifying one direct operand. The size of operand is 32 bits.
 The Main Memory of the machine is of size 224 words.
 The three consecutive instructions are placed starting from memory location (C450AF)h ; operand A is at location (F01000)h and contains a value (11AB234F)h, Operand B is at location (F01001)h and contains a value (11122350)h and operand C is at location (F01001)h and contains a value (00000000)h.
 The AC, IR, MAR and MBR registers are of size 32 bits, whereas PC register is of size 24 bits.
The initial content of the PC register is (C450AF)h.
