In a memory mapped input/output _______ 1. the CPU uses polling to watch the control bit constantly, looping to see if a device is ready 2. the CPU writes one data byte to the data register and sets a bit in control register to show that a byte is available 3. the CPU receives an interrupt when the device is ready for the next byte 4. the CPU runs a user written code and does accordingly

A multiprocessor has a 3.3 GHz clock (0.3 nsec) and CPI = 0.7 when references are satisfied by the local cache. How much faster is an application which uses only local references versus when 2% of the references are remote the processor stall for the remote access is 200nsec ?
REAL MODE MEMORY ADDRESSING 1. In the real mode, show the starting and ending address of the segment located by the following segment register values (in hex): a) SR= DC28b) SR=FA91 2. Find the memory location addressed by the microprocessor, when operated in the real mode, for the following segment register and 80286 register combinations: a) DS=8EBC & DX=A3D7b) CS=DCAF & IP=FAC8 Appreciate your help. Thanks!
The MSP430 can move/copy a byte or a word at a time using the instructions mov.b and mov.w respectively. In particular, the instructions mov.b &source_address, R4 mov.w &source_address, R4 copy the byte or word that resides at the given address (&source_address) to the given destination (the core register R4 in the CPU). Which of the following instructions are valid? (a) mov.b &0x1C03, R4 (b) mov.w &0x1C02, R4 (c) mov.b &0x1C00, R4 (d) mov.w &0x1C05, R4

You are participating in a Hackathon and you have been assigned a task to add a module to a newly built microprocessor that finds the volume of a sphere given the radius. Device an assembly code using 0-address, 1-address and 2-address instruction format that does this task. Explain each instruction clearly to achieve the final result
A computer has a cache, main memory, and a disk used for virtual memory. If a referenced word is in the cache, 20 ns are required to access it. If it is in main memory but not in the cache, 60 ns are needed to load it into the cache, then the reference is started again. If the word is not in main memory, 12 ms (not ns) are required to fetch the word from disk, then the reference is started again. The cache hit ratio is 0.9 and the main memory hit ratio is 0.06. What is the average time in ns required to access a referenced word on this system?

5a) Memory management is one of the key functionalities of operating systems (OS). If you install an OS on a computer-based on the von Neumann architecture, determine how the OS will prevent conflict between data and instructions that are used on the computer. b) With the aid of a well-labeled diagram, explain how you would convert covert ports designated as A and B to output ports on a PIC microcontroller
Q1. Professor Mikka Singh of Harvard University has proposed a new atomic instruction named “Gurru”. The atomic instruction will work exactly like Semaphores except it will take 2 clock cycles to execute. He proposed that a on a multi-processor environment while the instruction Gurru will be executing on any one of the processor then all the other processors shall be halted. However, the Operating System Lab Engineers at Harvard are still confused about whether the newly proposed instruction will work or not. What are your thoughts?
