Consider a Direct Mapped cache with 32-bit memory address reference word addressable. Assume a 2 word block and a Cache size of 8 locations. Each location has one Block Starting with an empty cache assume the following memory address references in the corresponding order Word Addresses in Main Memory Address 3180 43 2 191 88 190 14 181 44 186 253 What is block offset in cache of the underlined reference above? Select one: O a. 0 O b. 1 O c. 2 O d. 3 O e. 4 Consider a Direct Mapped cache with 32-bit memory address reference byte addressable. Assume a 2 word block and a Cache size of 16 Words.
