What is burst?mode operation (in the context of a cache memory)?
What will be an ideal response?
Burst?mode operation ties together two features of cache and DRAM. Cache memory uses lines as the minimum
transfer size between cache and memory (the idea is that data items should fit in a single cache line). Typically, a
line is 32 bytes, which means that 32 bytes have to be loaded following a miss.
Some DRAM’s have a burst mode operation where an address is used to make an access and then successive
words can be read without providing a new address because the memory has an internal sequencer. This feature
allows the memory to supply a burst of data during a cache refill.

Answer the following statements true (T) or false (F)
1. In an if... structure, the only possible outcomes are either: a block of statements are executed or nothing is executed. 2. A valid test condition could be (x = 10), assuming x is an integer variable. 3. The following test condition for an if... structure will be true if x = 2: ``` if(x < 5 && x > 10) ``` 4. The result of any test condition is always either true or false. 5. The following test condition will evaluate to true if x = 5: ``` if(x < 3 || x == 5) ```
