Answer:
True
Explanation:
An opcode is the part of instruction which specifies the operation to be performed by the instruction.
In general, the opcode also provides information about the number and type of operands.
For example, let us consider the MIPS instructions for addition.
- ADD reg_dest, reg_src1, reg_src2
This instruction adds the contents of registers reg_src1 and reg_src2 and stores the result in reg_dest.
- Whereas, ADDI reg_src, reg_dest, value
This instruction adds the value to the content of reg_src and stores the result in reg_dest.
As we can see the opcode type indicates the operand type, number and semantics.
Answer:
3.1 ns ; 1.25 ; 3.097
Explanation:
Given :
IF, 3 ns;
ID, 2.5 ns;
EX, 2 ns;
MEM, 3 ns;
WB, 1.5 ns.
Use 0.1 ns for the pipelineregisterdelay
maximum time required for MEM = 3 ns
Pipeline register delay = 0.1 ns.
Clock cycled time of the pipelined machine= maximum time required + delay
3ns+0.1 ns = 3.1 ns
2.) for stall after every 4 instruction :
CPI of new machine :
(1 + (1 /4)) = 1 + 0.25 = 1.25
3.)
The speedup of pipelined machine over the single-cycle machine is given by :
Average time per instruction of single cycle ÷ average time per instruction of pipelined
Clock time of original machine = 12ns
Ideal CP1 = 1
CPI of new machine = 1.25
Clock period = 3.1 ns
(12 * 1) / (1.25 * 3.1) = 12 / 3.875
= 3.097
D. Speed up will equal the number of stages in the machine
Answer:
def make_keeper(n):
"""Returns a function which takes one parameter cond and prints
out all integers 1..i..n where calling cond(i) returns True.
>>> def is_even(x):
# Even numbers have remainder 0 when divided by 2.
return x % 2 == 0
>>> make_keeper(5)(is_even)
2
4
"""
def fun(cond):
for i in range(1,n):
if(cond(i)):
print(i)
return fun
Explanation:
- Define a function called fun that takes cond as input.
- loop from 1 to n and display the value if it meets the requirement.
