Questions 2 : Assume there are three small caches, each consisting of four one-word blocks. On cache is direct-mapped, a second is two-way set-associative, and the third is fully associative. Find the number of hits for each cache organization given the following sequence of block addresses: 0, 8, 6, 5, 10, 15 and 8 are accessed twice in the same sequence. Make a tabular column as given below to show the cache content on each of columns as required. Show all the pass independently pass. Draw as many numbers Assume the writing policy is LRU. Memory location Hit/Mis Add as many columns as required

  Answer : Sequence of Block Addresses: 0, 8, 6, 5, 10, 15, 8 (accessed twice in the same sequence) Cache Configurations: Direct-Mapped Cache : 4 blocks Two-Way Set-Associative Cache : 2 sets with 2 blocks each Fully Associative Cache : 4 blocks Simulation: Direct-Mapped Cache: Access Address Index Cache Content Hit/Miss 1 0 0 0 Miss 2 8 0 8 Miss 3 6 2 8, 6 Miss 4 5 1 8, 6, 5 Miss 5 10 2 8, 10, 5 Miss 6 15 3 8, 10, 5, 15 Miss 7 8 0 8, 10, 5, 15 Hit 8 0 0 0, 10, 5, 15 Miss 9 8 0 8, 10, 5, 15 Miss 10 6 2 8, 6, 5, 15 Miss 11 5 1 8, 6, 5, 15 Hit 12 10 2 8, 10, 5, 15 Miss 13 15 3 8, 10, 5, 15 Hit 14 8 0 8, 10, 5, 15 Hit Direct-Mapped Cache Hits: 3 Two-Way Set-Associative Cache: Access Address Index Set Content Hit/Miss 1 0 0 (0, -) Miss 2 8 0 (0, 8) Miss 3 6 1 (0, 8), (6, -) Miss 4 5 1 (0, 8), (6, 5) Miss 5 10 0 (10, 8), (6, 5) Miss 6 15 1 (10, 8), (6, 15) Miss 7 8 0 (10, 8), (6, 15) Hit 8 0 0 (0, 8), (6, 15) Miss 9 8 0 (0, 8), (6, 15) Hit 10 6 1 (0, 8), (6, 15) Hit 11 5 1 (0, 8), (5, 15) M

Answer:   a. Identify the most likely reason why I could not enter the execute stage until the fourth cycle. One likely reason an instruction couldn't enter the execute stage until the fourth cycle is due to data hazards or resource conflicts: 1. Data Hazards: If the instruction depends on the result of a previous instruction that hasn't completed yet, it cannot proceed to the execute stage. This is often referred to as a Read After Write (RAW) hazard. 2. Resource Conflicts: If the required functional unit for execution (e.g., an ALU) is occupied by another instruction, the instruction will have to wait until the resource becomes available. b. Will "in-order issue/out-of-order completion" or "out-of-order issue/out-of-order completion" fix this? If so, which? Explain In-order issue/out-of-order completion  might help if the problem is related to instructions that can complete earlier being delayed by instructions that take longer to execute. This allows the
