The Pentium processor used a ___ architecture, which implies that it has two pipelines. The first pipeline, known as the ___ pipeline, can handle any instruction. The second pipeline, known as the ___ pipeline, can only handle ___instructions. Floating point instructions are first placed in the ___ pipeline, where they eventually are placed in the floating point unit: an exception to this rule is that the ___ instruction can stay in the u pipeline since it involves only ___ the operands, i.e. no floating-point operations are taking place during the instruction's execution. Using this type of architecture with two pipelines, the Pentium can achieve a maximum throughput of ___ (how many?) instructions per clock. You are working on some code, modifying the code that someone else wrote. When the following procedure executes, what happens? We discussed the Columbia Space Shuttle accident, especially from an engineering/operational standpoint. Circle all that apply regarding the Columbia tragedy: a. Columbia exploded upon re-entry b. management was swift to address the concerns raised by engineering teams while Columbia was still on-orbit c. The Columbia accident was the first ever recorded incident at NASA d. The damage was due to a pressure valve erupting e. Columbia's electronic control systems worked flawlessly, but couldn't control the orbiter since the damage was so great f. the reinforced carbon-carbon (RCC) panels were not tested for brittleness g. The accident report states that a rescue attempt would have likely been successful
