Answer:
a) the average CPI for machine M1 = 1.6
the average CPI for machine M2 = 2.5
b) M1 implementation is faster.
c) the clock cycles required for both processors.52.6*10^6.
Explanation:
(a)
The average CPI for M1 = 0.6 x 1 + 0.3 x 2 + 0.1 x 4
= 1.6
The average CPI for M2 = 0.6 x 2 + 0.3 x 3 + 0.1 x 4
= 2.5
(b)
The average MIPS rate is calculated as: Clock Rate/ averageCPI x 10^6
Given 80MHz = 80 * 10^6
The average MIPS ratings for M1 = 80 x 10^6 / 1.6 x 10^6
= 50
Given 100MHz = 100 * 10^6
The average MIPS ratings for M2 = 100 x 10^6 / 2.5 x 10^6
= 40
c)
Machine M2 has a smaller MIPS rating
Changing instruction set A from 2 to 1
The CPI will be increased to 1.9 (1*.6+3*.3+4*.1)
and hence MIPS Rating will now be (100/1.9)*10^6 = 52.6*10^6.
Answer:
Option b It executes a new process, which runs at the same time as the parent
Explanation:
The exec is one of the Java Runtime methods which is used to create a new process and run it as an separate process. Exec method executes the string command that we place inside the bracket. For example,
Process proc = Runtime.getRuntime().exec("Notepad.exe");
The statement above offers a convenient way to open the another computer software such as Notepad when running the program.
The correct answer is A: Ctrl and Page Up or Page Down keys.
Ctrl + Page Down - from left-to-right
Ctr + Page Up - from right-to-left
It is history list.But still you can check it by yourself
Answer:
The use of an x-ray machine is used to take pictures of dense tissues such as teeth or bones. This is because bones absorb the radiation more than the less dense soft tissue. X-rays from a source pass through the body and onto a photographic cassette.
