Explain the consequences of having a computer without an operating system. What is the purpose of an interrupt handler in an operating system? A group was hired to come up with techniques to boost a computer's performance. One of the participants proposed that the cache in the machine with L1, L2, and L3 be increased in size. Do you agree with this statement? Explain.

How does pipelining improve CPU efficiency? What’s the potential effect on pipelining’s efficiency when executing a conditional BRANCH instruction? What techniques can be used to make pipelining more efficient when executing conditional BRANCH instructions?
What are the benefits of assigning process execution to the I/O queue first when it is possible to do so? What do you think will take place in the event that the I/O is interrupted? Will this have an effect on the maximum burst rate that the CPU is capable of? I'm not sure I understand what you mean by that.
The Stack is one of the several forms of memory in an 8086 microprocessor. You are expected to investigate the issues raised below and provide thoughtful answers.1. Provide a scenario in which stack memory and the associated instructions are used (PUSH, POP)
When it comes to process execution, what is the advantage of first allocating it to the I/O queue and then pushing it to the CPU when it is ready? What, in your opinion, will happen if the I/O is not completed correctly? Is the CPU burst going to be affected? What do you mean?
Question 6 Suppose you have a RISC machine with a 1.6 GHz clock (i.e., the clock ticks 1.6 billion times per second). This particular computer uses an instruction cache, a data cache, an operand fetch unit, and an operand store unit. The instruction set includes simple instructions with the following timings: set reg, immed 2 clock cycle 2 clock cycles 2 clock cycle 4 clock cycles 3 clock cycles loop label add reg, immed add reg, reg load reg, mem Assume that the following code franent is used to sum the element of a numeric array. If the initialization code has already executed (i.e. the SET instructions have already finished execution) how many array elements can be processed in 5 ms? Round your answer to the nearest integer. Recall that 1 ms = 0.001 seconds. Also assume that there are no physical memory limitations, implying that the array can be as large as desired. ri, e r2, MAX_SIZE ;initialize loop counter r3, @list initialize sum set set set initialize array pointer more: load…
Consider a computer with cache, DRAM, HDD memory hierarchy. The hit rate of cache is 90% and DRAM is 95%. Read latencies of cache, DRAM, and HDD are 5ns, 100ns, and 1ms respectively. What is the average latency of executing an instruction involving a memory read? Express your answer in micro-seconds. Round it to the nearest integer. Enter your answer here
please answer with proper explanation and step by step solution. Question As a simple model of a bus-based multiprocessor system without caching, suppose that one instruction in every four references memory, and that a memory reference occupies the bus for an entire instruction time. If the bus is busy, the requesting CPU is put into a FIFO queue. How much faster will a 64-CPU system run than a 1-CPU system? Note: Don't copy paste from online website.
Q6: A digital computer has a memory unit with 24 bits per word. The instruction set consists of 110 different operations. All instructions have an operation code part (opcode) and an address part (allowing for only one address). Each instruction is stored in one word of memory. (a) How many bits are needed for the opcode? (b) How many bits are left for the address part of the instruction? (c) What is the maximum allowable size for memory? (d) Can we extend this instruction set by adding new 10 instructions and keeping the same length of opcode part? (e) Determine the type of this instruction set: stack-based ISA or accumulator- based ISA or general purpose registers-based ISA?
When allocating process execution to the I/O queue, what are the advantages of doing so first? If the I/O is interrupted, what do you believe will happen? Will this have an impact on the CPU's burst rate? What do you mean by that?
When a CPU sends an interrupt, it is obliged to halt whatever it is doing in order to respond to the signal. I'm interested about the reasoning of halting the procedure in order to finish the assignment. Let's start with the process of interrupting, and then we'll go on to the process of executing. explain?
Explore the concept of superscalar and out-of-order execution in ALU operations. How do these techniques improve processor performance, and what are their limitations?
If a CPU issues a 32-bit address on the address bus, and the computer uses the high-order 12 bits to access the memory map, with the remaining address lines going directly to memory: a) Exactly how many pages of memory does this computer have? b) What is the size of each page?
