CS232 Mid-term 2 Review 1 Review for Mid-term Exam 2 Facts about the organization: Exam takes 50 minutes. No written references or calculators are allowed. Pencils are encouraged. To receive any partial credit, show your work and comment any code. 2 Things to know for the Exam ( an incomplete list ) 1. Generic datapath concepts Tracing instructions through the datapath ( e.g. , mark all wires active during the execution of add instructions) Specifying control signal values for some instructions Adding new instructions ( but not emphasized this semester ) Computing the cycle time for a given datapath 2. Single-cycle Datapath 3. Pipelining and the Pipelined Datapath Ideal speedup and the reasons that it is not achieved Dependences, data hazards, and forwarding (which cases can be handled?)

Unformatted text preview: Control hazards, branch resolution, branch prediction, and stalling 4. Performance Components of processor performance: number of instructions, CPI, clock period Computing speedup Throughput vs. Latency Amdahls Law 5. I/O programming and interrupts Memory-mapped I/O Understand the structure of the interrupt handler & what the parts do (no need to memorize anything.) 6. Other topics Endianness (but we dont expect you to memorize which is little and which is big) 7. Things previously covered, that we didnt cover this semester: Floating Point Representations (single-precision IEEE 754), now left to CS 357 Multi-cycle implementation (only of historical importance) 8.
