The plan for this revised edition has been thoroughly reviewed by eminent faculties of various technical universities across the country and their inputs have been incorporated to enhance the contents of this edition. Features 1. New chapters on Introduction to architecture and Peripheral devices 2. New sections on master-slave flip flop, counters, code converters and horizontal and vertical micro programming 3.

Introduces Multi bus organization, memory addressing and memory technology 4. Over new multiple choice questions and updated exercise problems. Step-1 : Read the Book Name and author Name thoroughly.

Go back to step 1.

From Table 5. The first I is an address symbol and the second I as the Indirect bit. Answer: Yes, it can be used for this assembler. Such a label has no meaning and constitutes an error. To detect the error, modify the flow chart of Fig. Will be shifted left into XH which has zero initially. The partial product will contain two locations PL and PH initially zero.

Multiplier is in location Y. Flow-Chart : - 40 - 6. Thus, BL is complemented and incremented while BH is only complemented. Microprogram is a program for a sequence of microoperations. The control unit of a microprocessor can be hardwired or microprogrammed, depending on the specific design. A microprogrammed computer does not have to be a microprocessor. Micro instruction - an instruction stored in control memory. Micro program - a sequence of microinstructions.

Micro code - same as microprogram. Both use F1 7. The subroutine must read the operand into DR. INDR 2 : 7. Cannot read and write at the same time. Cannot add and subtract at the same time.

The RET will be executed independent of S. The MAP is executed irrespective of Z or The decoder signals propagate at the same as the muxs. Computational type Fetch instruction Fetch effective address Fetch operand 3 memory references Branch type Fetch instruction Fetch effective address and transfer to PC 2 memory references.

Subroutine call — Branch to subroutine and then return to calling program. Program interrupt — Hardware initiated branch with possibility to return. Then use a scheme similar to the one described in conjunction with the adder pipeline in Fig.

Delayed branch is a software procedure. Increment R3 4. Segment FO: Read M[]. Segment DA: Decode increment instruction. Segment FI: Fetch the store instruction from memory. Array 2: 1, 5, 9, 13, …, ; Array 3: 2, 6, 10, …, Array 4: 3, 7, 11, …, Case 1.

Case 3. Case 4. As A It is necessary to show that maximum product is less than or equal to r2n — 1. The first test value is 01 The second test value is 01 The third test value is 92 01 The fourth test value is 92 93 01 etc. Mark the bits of A in groups of two starting from left. Bn If signs are unlike — the one with a 0 plus is larger.

If signs are alike — both numbers are either positive or negative When 2 numbers of n bits each are multiplied, the product is no more than 2n bits long-see Prob. Apply carry directly to E. At the termination of division, B is added to the negative difference. Output flag is a bit in status register.

Output flag to indicate when transmitter register is empty. Input flag to indicate when receiver register is full. Enable interrupt if any flag is set. Parity error; 5 Framing error; 6 Overrun error. From Table The state of the CPU to be saved is more complex. At the beginning of the service routine, check the value of the return address in the stack. If it is an address within the source service program, then the same source has interrupted again while being serviced.

The priority level of the other sources corresponds to the order in which the flags are checked. Bits to the control register to specify a write operation. CPU responds with a BG bus grant. Contents of DMA address register are placed in address bus. Repeat steps for each data word Transferred. DMA usually transfers data from a device that cannot be stopped since information continues to flow so loss of data may occur.

The terminal responds with either ACK acknowledge or NAK negative acknowledge or the terminal does not respond during a timeout period. If the processor receives an ACK, it sends a block of text.

Total of 24 pins. Each bank of 32K bytes are selected by addresses FFF. Each output of the register selects one of the 8 bank of 32K bytes through a chip-select input.
