Answer the following statements true (T) or false (F)
1. Resources include: memories, caches, buses, and register-file ports. 2. Machine parallelism exists when instructions in a sequence are independent and thus can be executed in parallel by overlapping. 3. The simplest instruction issue policy is to issue instructions in the exact order that would be achieved by sequential execution (in-order issue) and to write results in that same order (in-order completion). 4. In-order completion requires more complex instruction issue logic than out-of-order completion. 5. The reorder buffer is temporary storage for results completed out of order that are then committed to the register file in program order.
