Answer:
Explanation:
(a) Given data:
Instruction pipeline with 4 phases.
80 instruction
The number of cycles if the processor were pipelined :
80-1 = (79) instruction takes only 1 extra cycle to complete.
So, cycles counts = 4 + (79) = 83 cycles.
The number of cycles if the processor were not pipelined.
Each instruction takes 4 cycles to complete.
So, cycle counts = 80 * 4 = 320 cycles.
(b) One of the main problems of conditional branching in pipelines is the delay it gives even after the branch target buffer.
In pipeline, conditional branches depend on the codes which are still in estimation.
(c) Two ways to deal with problem arising due to conditional branching are as follows :
1. Delayed Branching
2. Multiple Condition Codes
The problem that Mitra identifies in education is that kids don't go to school, don't know what a computer or the internet is. Teachers don't want to go to places where they're needed the most.
The cd command, also known as chdir (change directory), is a command-line shell command used to change the current working directory in various operating systems. It can be used in shell scripts and batch files.
