Dynamic behaviour
Static behaviour
Speed
Two processors A and B have clock frequencies of 700 Mhz and 900 Mhz respectively. Suppose A can execute an instruction with an average of 3 steps and B an execute with an average of 5 steps. For the execution of the same instruction which processor is faster ?
A
B
Both take the same time
Insuffient information
To which class of systems does the von Neumann computer belong?
SIMD (Single Instruction Multiple Data)
MIMD (Multiple Instruction Multiple Data)
MISD (Multiple Instruction Single Data)
SISD (Single Instruction Single Data)
To provide increased memory capacity for operating system, the
virtual memory is created
cache memory is increased
memory for OS is reserved
Additional memory is installed
The word size of the microprocessor refers to
the amount of a information that can be stored in a byte
the amount of a information that can be stored in a cycle
The number of machine operations performed in a second
the maximum length of an English word that can be input to a computer
The ultimate goal of a compiler is to,
Reduce the clock cycles for a programming task.
Reduce the size of the object code.
Be versatile.
Be able to detect even the smallest of errors.
The output of a gate is low when at least one of its input is low . It is true forA
AND gateB
OR gateC
NAND gateD
NOR gate
The most common addressing techiniques employed by a CPU is
immediate
direct
indirect
all of the above
The maximum integer which can be stored on a 8 bit accumulator is
112
200
255
224
The iconic feature of the RISC machine among the following are
Reduced number of addressing modes
Increased memory size
Having a branch delay slot
All of the above
The expression delayed load is used in context of
processor-printer communication
memory-monitor communication
pipelining
none of the above
The cost of a parallel processing is primarily determined by :
Time Complexity
Switching Complexity
Circuit Complexity
None of the above
The concept of pipelining is most effective in improving performance if the tasks being performed in different stages :
require different amount of time
require about the same amount of time
require different amount of time with time difference between any two tasks being same
require different amount with time difference between any two tasks being different
The clock rate of the processor can be improved by,
Improving the IC technology of the logic circuits
Reducing the amount of processing done in one step
By using overclocking method
All of the above
The average number of steps taken to execute the set of instructions can be made to be less than one by following
ISA
Pipe-lining
Super-scaling
Sequential
The advantage of RISC processor over CISC processor is that
The hardware architecture is simpler
An instruction can be executed in one cycle
Less number of registers accommodate in chip
Parallel execution capabilities
The access time of memory is ............... the time required for performing any single CPU operation.
Longer than
Shorter than
Negligible than
Same as
The 16- bit registers in 8085 is
general purpose register
accumulator
stack pointer and program counter
all of the above
Te devices connected to a microprocessor can use the data bus:
all the time
at regular interval of time
only when it's sending or receiving data
when the microprocessor is reset
