Part I
Consider a computer that you have used or now use. (You may make an assumption on word size if needed.)
- How large is the memory of the computer?
- How long is a word in the computer above?
- How many bits are required to address the bytes in that memory?
- How many data lines are required to read data from the computer memory?
Part II
- Does your computer have cache?
- If so how big is it?
- How does your cache size compare with the size of main memory?
- Do you know what kind of cache it is?
- How did you find out about your computer's cache?
Make an assumption that your cache is either:
- Fully associative
- Direct mapped
- Two-way set-associative
- Four-way set-associative
Using the relationships in Part I above, determine:
the size of the Tag and Word for Associative cache;
OR
the size of the Tag, Line, and Word for Direct-Mapped Cache ;
Or
the size of Tag, Set, and Word for K-Way Set-Associative Cache.
You may make any assumptions necessary including the number of Words in each block (recommend 2 or 4 or 8)
Part III
Given the following:
- Logical Memory size of 1000
- Physical Memory size of 2000
- Page (and frame) size of 100
- Block A contains data for a program
Select Block A's size and its starting point in both memories. Then write the page table for Block A based on your selections.
I know some of these answers, i have bolded the ones I do not understand.
Could you help me understand how you get the answer?
