Answer:
We can not improve CPI of FP instructions when we run the program two times faster because it would be negative.
Explanation:
Processor clock rate = 2 GHz
Execution Time = ∑
Clock cycles can be determined using following formula
Clock cycles = ( x No. FP instructions )+ (
x No. INT instructions) + (
x No. L/S instructions ) + (
x No. branch instructions)
Clock cycles = ( 50 x x 1) + ( 110 x
x 1) + ( 80 x
x 4) + ( 16 x
x 2)
Clock cycles = 512 x 10⁶
So,Initial Execution time for FP instructions is,
=
Initial execution Time = 256 x 10⁻³
For 16 processors ,
clock cycle = 512 x 10⁶
Execution Time = 256 x 10⁻³
To run the program two times faster, half the number of clock cycles
( )= (
x No. FP instructions )+ (
x No. INT instructions) + (
x No. L/S instructions ) + (
x No. branch instructions)
x No. FP instructions = (
) -[ (
x No. INT instructions) + (
x No. L/S instructions ) + (
x No. branch instructions)]
x 50 x
= (
) - [ ( 110 x
x 1) + ( 80 x
x 4) + ( 16 x
x 2)]
x 50 x
= - 206 x
= - 206 x
/ 50 x
= - 4.12 < 0
Answer:
Cc= 12.7 lb.sec/ft
Explanation:
Given that
m = 22 lb
g= 32 ft/s²
x= 4.5 in
1 in = 0.083 ft
x= 0.375 ft
Spring constant ,K
K= 58.66 lb/ft
The damper coefficient for critically damped system
Cc= 12.7 lb.sec/ft
