At the end of this page, you should find the code that not only generates the sequences for the direct cache project, but also calls the requestMemoryAddress() and getPercentageOfHits() functions. It should be inserted in your code immediately after the memory is initialized. In my sample code, this is right after the loop that looks like:
for (int i = 0; i < powerOfTwo(NUMBER_OF_BITS_IN_ADDRESS); i++)
memory[i] = (65535 - i) & EIGHT_BIT_MASK;
To use the code below, you'll need to define either SEQ1, SEQ2, SEQ3, SEQ4, or SEQ5 to select one of the five sequences. The sequences are meant to simulate the following:
Here's the code:
#define SEQ1
//#define SEQ2
//#define SEQ3
//#define SEQ4
//#define SEQ5
#ifdef SEQ1
