Write an assembly program with the following specifications. a). in the main block, you should have two registers r4 and r5. they should be checked in an infinite loop. if r4 is greater than r5, then the greater subroutine will be called. if r4 is less than r5, then the less subroutine will be called. if r4 equals r5, then no operations will be done

Suppose we have a byte addressable computer that has a 32-byte cache with 8 bytes per block. the memory address is 8 bits long. the system accesses memory addresses (in hex) in this exact order: 6e, b9, 17, e0, 4e, 4f, 50, 91, a8, ab, ad, 93, and 94. (a) assuming the cache is direct mapped, what memory addresses will be in cache block 2 after the last address has been accessed? (b) assuming the cache is direct mapped, what is the hit ratio for the entire memory reference sequence given, assuming the cache is initially empty? (c) assuming the cache is 2-way set associative with a lru replacement policy, what is the hit ratio?
