Cache and Memory Mapping

Part I

Consider the computer memory that you used for Part II of Discussion Topic 3; and select one of the cache strategies listed below

•  Fully Associative cache
•  Direct-Mapped cache
•  4-way Set-Associative cache

Then:

• State the size of main memory,
• State the number of bits needed to address main memory.
• State the size the cache memory you picked, and
• the size of a block of memory. (You may make an assumption on number of words in each block; I recommend 2 or 4 or 8.)

Part II 

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 a 4-Way Set-Associative Cache.

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 translation table for Block A based on your selections.

 See "Example of Logical and Physical Memories" in Advanced Systems Concepts for the layout of both memories, a Block A of size 200, and a page translation table.

Part IV

 Discuss the pros and cons of paging.
