Simplify the following function using K-map: F(A, B, C, D) = Σ (1, 3, 4, 7, 11, 13) Draw the circuit for the resultant function using NAND gates.

Perform the following conversion of numbers: 
 i) Decimal (345654398)10 to binary and hexadecimal
 ii) Hexadecimal (FFEEDDCBA)h into Octal.
 iii) String “Computer Organisation” into UTF 8
 iv) Octal (6754632)O into Decimal

Draw three more diagrams, each showing the state of 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 execution of instruction. Show all the addresses and values in hexadecimal notations.

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 content of all the stated registers.

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:
 LODA A ; Load the content of Memory location A into the Accumulator Register.
 ADD B ; Add the content of memory location B from Accumulator Register.
 STOR C ; Stores the content of 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 16 bits in length.
 Each instruction is of length 32 bits with 16 bits for operation code (opcode) and 16 bits for
specifying one direct operand.
 The Main Memory of the machine would be of size 216 words.
 The three consecutive instructions are placed starting from memory location (11FE)h ;
operand A is at location (1FFF)h and contains a value (4321)h, Operand B is at location
(2000)h and contains a value (1FFE)h and operand C is at location (2001)h and contains a
value (0000)h.
 The AC, PC, MAR and MBR registers are of size 16 bits, whereas IR register is of size 32
bits. The initial content of the PC register is (11FE)h.

IGNOU wants to deliver CIT programme in multimedia form. Propose a plan to develop a CIT block in multimedia form. Assume a section of a unit to be smallest entity. Then propose text, graphics, audio, video, animation required for that section. You can also think of linking several non-linear sections.
