SQL Query

Structured Query Language is the full form of SQL. It is one of the standard languages to deal with the relational database. It is used to insert, update, delete, and search the records stored in a RDBMS. The relational databases are created and managed by using SQL.

6. Suppose you had a computer that, on average, exhibited the following properties
on the programs that you run:
Instruction miss rate: 2.5%
Data miss rate: 8.0%
Percentage of memory instructions: 25%
Miss penalty: 100 cycles
There is no penalty for a cache hit (i.e. the cache can supply the data as
fast as the processor can consume it). Assume also that a cache-block is one
word. You are planning to upgrade the memory to one that is twice as fast. How
much faster is the system with the new memory than the original system?

A 2-way set associative cache consists of four sets. Main memory contains 2K blocks of eight words each. Show the main memory address format that allows us to map addresses from main memory to cache. Be sure to include the fields as well as their sizes. Compute the hit ratio for a program that loops 6 times from locations 8 to 51 in main memory. You may leave the hit ratio in terms of a fraction. Please show details how you obtain the result.
Suppose a computer using direct mapped cache has 232 byte of byte-addressable main memory, and a cache of 1024 blocks, where each cache block contains 32 bytes. a) How many blocks of main memory are there? b) What is the format of a memory address as seen by the cache, i.e., what are the sizes of the tag, block, and offset fields? c) To which cache block will the memory address 0x000063FA map?
A computer of 32 bits has a cache memory of 64 KB with a cache line size of 64 bytes. The cache access time is 20 ns, and the miss penalty is 120 ns.

Hi, professor! I'm not sure about the following question. Consider a cache memory that provides three hundred 16-byte blocks. Now consider that you are processing all the data in a two-dimensional array of, say, four hundred rows by four hundred columns, using a pair of nested loops. Assume that the program stores the array column by column. You can write your program to nest the loops in either direction, that is, process row by row or column by column. Explain which way you would choose to process the data. What is the advantage? Conversely, what is the disadvantage of processing the data the other way? What effect does choosing the incorrect way have on system performance?
7. A 32-bit computer has a data cache memory with 8 KB and lines of 64 bytes. Calculate the hit ratio of this program. double a [1024], b[1024], c[1024], d[1024]; // A double occupies 8 bytes // the array are consecutively stored // in memory for (int i = 0; i < 1024; i++) a[i] = b[i] + c[i] +d[i]; The cache uses a direct mapped function and write-back policy. The cache uses a full associative cache with LRU as replacement algorithm. The cache uses a 2-way associative cache and a 4-way associative cache with LRU as replacement algorithm.
Is there anything that should take place in the event that a processor sends a cache-unfulfilled request at the same time as a block is being sent back to main memory from the write buffer?
This function will be able to determine the fields in a log entry it needs to look at in order to do its job properly. The following line of code computes the average number of cache misses for each item in the cache when 64-byte cache blocks are used without any prefetching being performed by the program.
Given that a 4-way set associative cache memory has 64 KB data and each block contains 32 bytes. The main memory capacity is 4 GB. a. Find the number of bits for the main memory address. ANSWER: bits b. How many blocks are there in a set? ANSWER: blocks c. How many sets the cache has? ANSWER: d. The main memory address format is => | Tag: e. Which set will be mapped by the main memory address 458195h. ANSWER: sets bits | Set: bits | Word: bits | (in decimal)
1. Concerning the memory hierarchy, there is a trade-off among the three key characteristics: capacity, access time, and cost. What is the relationship between these three? 2. What happens if a computer system only contains registers and main memory, but no cache? Justify your answer 3. The replacement algorithm chooses (within the constraints of the mapping function) which block to replace when a new block is to be loaded into the cache and the cache already has all slots filled with other blocks. Suggest a strategy that has at least one advantage over the least-recently-used (LRU) algorithm. Justify your answer
Consider a fully-associative cache of size 4. Each slot in the cache can have just one item (i.e. the line size is 1 item). The cache is empty to start with. The cache uses an LRU replacement policy: every slot has a counter; every time a slot is accessed, a global counter is incremented and the value is stored in the slot counter; the slot with the lowest counter value is chosen for replacement. Sequence Id 1 2 3 4 5 6 7 8 10 Address Ox0012 0x0014 Ox0016 Ox0018 0x0016 0x0012 0x0020 Ox0022 0x0014 Ox0012 Hit/Miss Accesses 1 to 10 are respectively: Select one: O a. Miss, Miss, Miss, Miss, Hit, Hit, Miss, Miss, Miss, Miss O b. Miss, Miss, Miss, Miss, Hit, Hit, Miss, Miss, Hit, Hit O. Miss, Miss, Miss, Miss, Hit, Hit, Miss, Miss, Hit, Miss O d.

When the processor receives a request that it cannot fulfill from the cache, it sends a write buffer to return the unsatisfied block to main memory. So, what ought to be done here?
