Suppose a malloc implementation returns 8-byte aligned addresses and uses an implicit free list. Blocks have a 32-bit header, where the low-order bit of the header is used to indicate whether the block is allocated (1) or free (0). Furthermore, the block size (which includes the header, payload, and any necessary padding) is rounded up to the nearest multiple of 8, and this size (in bytes) is stored in the header. Assume any padding must be at the end of the block. If we call to malloc(1), what block size will be allocated, in bytes?

Create a program in C++ which simulates a direct cache. The memory array that contains the data to becached is byte addressable and can contain 256 single byte entries or lines. The cache has only 8 entriesor lines. The Data field in each line of the cache is 8 bits. Since the data stored in each line of the cache isonly 8 bits, there is no need for a line field. Only a tag field is needed which is log2(256) = 8 bits.The memory array can be filled with any values of your choice. The program should work by taking userinput of a memory address (index). This input represents the memory data that should be cached.Check the cache to see if the item is already cached. If it is not, your program should counta cache miss, and then replace the item currently in the cache with the data from the inputted address.Allow the user to input addresses (in a loop), until they so choose to end the program. The program should output the number of cache misses upon ending.
