Consider Prof. Vamshias writes a program given below and runs on a system which has 2-way set associative 16 KB data cache with 32 bytes block where each word size is 32 bits and LRU replacement policy used. If the base address of the array is 0 and initially the cache is empty then the number of data cache misses are there ________. (Assume integer takes 4 bytes)

int i,a[1024*1024],x=0;

 for(i=0;i<1024;i++)

    x +=a[i] + a[1024 * i];
