Properties of different architectures

Software architectures are the blueprint of a software system. They consist of all components involved in a system, relations between various components, the environment of operation, and the principle used in designing the software. In other words, software architecture shows the organization of different software structures and helps understand their behavior.

Find out whether a certain cache is inclusive or exclusive by looking at the contents of it.
Let's pretend that something unexpected happens: the CPU makes a partially-completed request to the cache at the same time as a block is being returned from the write buffer to main memory. The following steps need to take place.
Computer Science You are given a cache that has 16 byte blocks, 512 sets, and is 2-way set associative. Integers are 4 bytes. Give the C code for a loop that has a 100% miss rate in this cache but whose hit rate rises to almost 100% if you double the size of the cache. Do not assume the starting indexes of any arraysarrays.
Q1:.
How many fields can the specified log processing function access in a log entry? Calculating average cache miss rates per entry using 64-byte blocks and no prefetching is done using the following code.
Could you kindly go through the fundamentals of how a cache hierarchy is set up and how it works?
What does write back mean in terms of cache? Group of answer choices a. When an error occurs in memory, the cache is written back to the memory. b. When a bit in the cache is changed, the entire block is written to memory. c. When a line is evicted, the block it contains is written to memory.
3. The table below represents a stack stored in a contiguous block of memory cells (as discussed in the text). If the base of the stack is at address 0x10 and the stack pointer contains the value 0x12, what value is retrieved by a pop instruction? What value is in the stack pointer after the pop operation? Address 0x10 0x11 0x12 0x13 0x14 Contents 'F' 'C' 'A' 'B' 'E'
. Q: In this problem you are to compare reading a file using a single-threaded file server and a multithreaded server. It takes 15 msec to get a request for work, dispatch it, and do the rest of the necessary processing, assuming that the data needed are in a cache in main memory. If a disk operation is needed, as is the case one-third of the time, an additional 75 msec is required, during which time the thread sleeps. How many requests/sec can the server handle if it is single threaded? If it is multithreaded?
