Midterm paper of CS501_Advance Computer Architecture
Campus: VKHI02
Date: 28 November, 2011
1. What function is performed by the reset operation of a processor and differentiate Hard reset and Soft reset? [5 marks]
2. Write the Structural RTL for the mov instruction for uni-bus data path implementation.
mov ra, rb [3 marks]
3. Write the Structural RTL for shift right instruction. [Question was not exactly like that. Every thing was written[i mean structure was already written] we just have to arrange the sequences of the steps.][2 marks only :( ]
4. What is the use of "NOP" instruction in pipelining? [3 marks]
Ask As MCQs.
1). LPC: This control signal will enable write of the Program Counter, thus the new,
incremented value can be written into the PC if it is made available on the "in"
bus. Note that the ALSU is assumed to include an INC4 function.
2). Anything that interrupts the normal flow of execution of instructions in the
processor is called an exception.
3).What is the size of the memory space that is available to FALCON-A processor?
Select correct option:
2^8 bytes
2^16 bytes
2^32 bytes
2^64 bytes
4). What is the working of Processor Status Word (PSW)?
Select correct option:
To hold the current status of the processor.
To hold the address of the current process
To hold the instruction that the computer is currently processing
To hold the address of the next instruction in memory that is to be executed
5). What is the instruction length of the FALCON-E processor?
Select correct option:
8 bits
16 bits
32 bits
64 bits
6). Which one of the following portions of an instruction represents the operation to be performed?
Select correct option:
Address
Instruction code
Opcode
Operand
7). Which instruction is used to store register to memory using relative address?
Select correct option:
ld instruction
ldr instruction
lar instruction
str instruction
I don't know its answer but they are from topic: SRC instruction format.
8). Which type of instructions help in changing the flow of the program as and when required?
Select correct option:
Arithmetic
Control
Data transfer
Floating point
9). A MCQ about Power PC
10). which one of the following is 0-address based machine.
11). There was a very long MCQ not remember now but the options are [this is so strange.]
VCON
FCON
ACON
LCON
I already found all of them keywords on handouts but there is nothing like this.
