I will probably do nothing unless you miss several weeks of class.I require a note from the Dean as well as a signed note from a doctor saying that the illness is to serious for you to go to classA McKinley timestamp thing will not do01/14/19 CS 433 Luddy Harrison 7Policies: AttendanceAttendance is not requiredQuizzes are every other Thursday starting Sept 8.01/14/19 CS 433 Luddy Harrison 8ProjectsYou can do an extra-credit projectThis will change your grade by at most one letterI’m thinking of visual simulations of processors01/14/19 CS 433 Luddy Harrison 9Prof. Harrison’s Grade-Related Sympathy Diagram01/14/19 CS 433 Luddy Harrison 10A Note For Special StudentsIf things are going really badly for you …You aren’t attending classes or doing your workYou aren’t sure you are in the right degree program, or that you want a degree at allFor some other reason you are down and out… then you should come see me (really)No, I won’t give you a good grade!But I might be able to help you.01/14/19 CS 433 Luddy Harrison 11The BookI will follow it closely concerningPipeliningTomasculoCacheVirtual MemoryOtherwise I will not follow it closelyI find it to be old and funky but quaintIf I don’t lecture on material, it will not be tested or homeworked or quizzed01/14/19 CS 433 Luddy Harrison 12Goals and FocusProcessor ArchitectureTherefore dropping CA:AQA Chapters 7 (Secondary Storage) and8 (Interconnects)Mechanisms for PerformanceParallelismPipeliningData parallelismILPStaticDynamicMultithreadingMultiprocessingReduced Memory Latency / Increased Memory BandwidthCachingLatency HidingWide Memory InterfacesCurrent Processors as Examples (this list is only preliminary)MIPS (general purpose, embedded control)ARM (low-power general-purpose, e.g., PDAs)Intel IA32 (x86) (general purpose, embedded control, almost everything)IBM PowerPC (general purpose, embedded control, network processing)TI TMS320C6000 (C6x) (high-performance media and signal processing)ADI TigerSharc (cellular infrastructure, software radio)Intel IXA (network processing)01/14/19 CS 433 Luddy Harrison 13Skills You Will Develop1.
