uni-bus data path implementation. (5 Marks)
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. 2 marks
4. What is the use of "NOP" instruction in pipe lining? 3 marks
Some MCQs are as follows
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?
4). What is the working of Processor Status Word (PSW)?
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 vuzs
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?
6). Which one of the following portions of an instruction represents the operation to be performed?
7). Which instruction is used to store register to memory using relative address?
Helping topic: SRC instruction format.
8). Which type of instructions help in changing the flow of the program as and when required? vuzs.net
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,
I already found all of them keywords on handouts but there is nothing like this.
For any of the instructions that are a part of the instruction set of the SRC, there are cerain_________required; which may be used to select the appropriate function for the ALU to be performed, to select the appropriate registers, or the appropriate memory location.
FALCON-A processor bus has 16 lines or is 16-bits wide while that of SRC _____wide.
What is the instruction longth of the FALCON-A processor?
_________control signals enable the input to the PC for receiving a value that is currently on the internal processor bus.
Which one of the following is a bi-stable device, capable of storing one bit of information?
Which instruction is used to store register to memory using relative address?
Which field of the machine language instruction is the “type of operation” that is to be performed?
The instruction ___________ will load the register R3 with the contenets of the m\emory location M [PC+56]
___Add R3, 56
___lar R3, 56
___ldr R3, 56
___str R3, 56

which type of instructions help in changing the flow of the program as and when required?
Which one of the following registers holds the address of the next instruction to be executed?
Which one of the following is the memory organization of EAGLE processor?
The external interface of FALCON-A constists of a ______address bus and ______a data bus.
Type A of SRC has which of the following instructions? A) andi, instruction b) No operation or nop instruction c) lar instruction d) ldr instruction e) Stop operation or stop instruction
