other than the CPU within?
IN ANSWERING QUESTIONS 5-33 THROUGH 5-36,
SELECT FROM THE FOLLOWING LIST THE
CACHE MAPPING TECHNIQUE DESCRIBED IN
1. Direct mapping
2. Fully associative mapping
3. Set associative mapping
Is the most flexible cache mapping technique
with regards to where data can reside.
Combines the best cache mapping techniques.
Main memory locations can only be copied into
one location in cache.
If cache is full, a replacement algorithm is used
to decide which block gets replaced by new data.
What cache read method can be used to present
the cache and main memory with the reference
1. Look-aside, serial read
2. Look-aside, parallel read
3. Look-through, serial read
4. Look-through, parallel read
In a look-through read, the cache is checked last.
Optimum cache replacement would be psychic
and have perfect knowledge of the future. What
cache replacement policy, if any, comes closest
to the optimum cache replacement?
